How to add hard disk space. How to increase the capacity of drive C. How to resize or increase the capacity of the system drive (C:) Increase the capacity of the drive from

Each time there is less and less free space on drive C. The problem of memory exhaustion is common to all computers, even those with a HDD or SSD with a large amount of free space. At the same time, Windows cannot work normally when there is a shortage of memory, so it is imperative to ensure sufficient space for the system. There are two ways to achieve this goal: remove existing files or increase the disk size. IN this moment I'm more interested in the second direction - increasing disk space.

The problem appears due to one feature of Windows - a gradual increase in the size of the system and the constant addition of temporary files. Over time, system files, as well as temporary files, tend to take up more space. Everyone is guilty of this Windows versions, with no exceptions.

Initially, the lack of space can be corrected by deleting useless programs, temporary files, downloads, etc. All the same, the inevitable situation is when only important applications are left on the disk, and, alas, there is not enough space. Some users give up, but this is not worth doing, since the system begins to process requests very slowly, programs often crash, and errors become the norm.

To continue to use local applications normally, you need to provide enough free space on drive C. So, how to increase the capacity of the C drive? We'll tell you in our article.

How to clean a disk from garbage?

The easiest way to free up space is to remove all junk. If the problem of lack of space has appeared recently, it is still possible to get by only by deleting useless data. For some time this will be enough for normal operation of the system. You need to clean out the garbage in several stages.

Algorithm of actions is given below.

  1. We clean temporary files (they inevitably accumulate when all applications are running). The CCleaner program copes with the task efficiently and quickly. Just download the utility from the link, on the first tab click on the “Analysis” button, and then click on “Cleaning”.
  2. Removing useless files. By default, Windows browsers download all files to the “Downloads” section located on drive C. There may be a lot of unnecessary stuff here: software distributions for installation, outdated files, torrents, etc. It’s worth checking the sections where files are downloaded and deleting them everything is useless.
  3. Uninstalling programs. Many users go through 2, 5 or 10 applications in search of suitable ones. Having found good utility the search stops, but earlier installed programs remain in the system. They should be removed by going to the “Programs and Features” section, menu - “Control Panel”.
  4. Transfer media files to another drive. It is better to store photos, movies, music, games, etc. on drive D. Such files should be cut from drive C and moved to D.

How to increase the size of drive C at the expense of drive D?

Add free place to logical drive C really standard means Windows or through applications. The main disadvantage of the first method is the forced formatting of the partition. The programs cope with the same task, but without deleting files, so this option priority.

Using Aomei Partition Assistant

A free utility with a good reputation successfully copes with transferring space and saving data.

Its advantages include:

  • easy setup;
  • the ability to launch several actions at once;
  • reliable operation;
  • Russian interface.

The entire procedure is absolutely safe for your computer and hard drive.

Main functions of the program:

  1. creating and deleting logical drives;
  2. transferring free space between disks;
  3. formatting;
  4. merging, splitting, copying sections.

Of greatest interest to us is the transfer of free space.

To perform it, you should use the instructions:

  • download the application from website;
  • install and run the program;
  • right-click on the disk where there is free space intended for transfer and click on “Resize partition”;
  • Reduce space on drive D to create unallocated space.

Important! The slider should be moved from left to right, the freed volume should appear before the other data on the disk.

  • repeat step 3, but for drive C, and expand its space using the space on the right;
  • In the main window, click on the “Apply” button.

Healthy! The program supports deferred action, which means that no changes occur until you click “Apply”. Before starting the procedure, all changes can be corrected.

Using MiniTool Partition Wizard Free

This is another similar program that is not inferior to the previous one. Has the ability to move space without formatting disks. The only drawback is the English-language interface, but it is intuitive, so it’s quite difficult to get confused.

The method for adding free space to drive C is no different from the previous program. The instructions from the last section also apply to the MiniTool Partition Wizard. Using control points, you first need to reduce one disk, and then increase the other. If you need to allocate precise space, you can specify the desired volume in numbers (indicated in megabytes).

All of the above methods create free space on the C drive, so the reader can independently choose the method he likes. Typically, after the procedure, the system begins to work much faster and failures occur less frequently.

The first, most natural “devourer” of free space on your hard drive is the Windows operating system. During PC operation, a so-called paging file is used, into which the OS unloads files if there is not enough random access memory. It is not recommended to disable the use of the paging file, but a competent specialist can change its size if necessary.

Another "fruit" Windows operation- creating system restore points. The files needed to restore the operating system after a failure can take up a very large amount of the total disk space and are not always needed by the user. If you save important data to an external hard drive or flash drive, and installers of the programs you need to work are at hand, then you can disable system recovery altogether. If you need recovery points, use them periodically when system failures, then in the settings you can reduce their number, as well as the amount of space for them.

For Windows Vista or Windows 10, the path you need to follow to access the above settings is: “Start” -> “Settings” -> “Control Panel” -> “System” -> “System Protection”.

How to remove “garbage” after running various programs

Of course, the files that various programs create during the course of their work cannot be called garbage in the full sense of the word, but after obtaining the desired result, they can be cleaned quite painlessly. For example, you should clear your browser cache more often. After uninstalling programs, it is worth checking the location where it was installed and manually deleting folders and files that were created and not deleted automatically.

It often happens that one hard drive runs out of space, but another has plenty of it. Usually you run out of space on drive C, because... Initially, the least amount of memory is allocated for it when installing the OS. So what is the solution in this situation?

Let's look at two absolutely safe methods.

Method No. 1

If you have Windows 7 or 8 operating system on your PC, then everything is as easy as shelling pears for you. You can use the standard Disk Management utility, which is used to change and view hard disk partitions.

Method No. 2

If you are still “sitting” on XP or, even worse, on Vista, then in this case you need special programs. Personally, I advise - Acronis Disk Director or Partition Magic.

Now let's go through each method in more detail.

In the first case, the procedure is as follows:

Right-click (right mouse button) on the Computer icon on the desktop and go to Management in the context menu. A window opens, find and launch the utility - Disk Management.


Next, let’s assume the most common case, when we “expand” drive C at the expense of drive D. To do this, find drive D in the window, right-click and select - Shrink volume. A window will open where you will need to specify the size of memory that we want to transfer to the system disk. We drive it in the item - Size of compressed space (MB).

After this, a free memory area will appear on our hard drive, which we can transfer to any other drive, in our case, drive C. To do this, then right-click on it and select - Expand volume. The Volume Expansion Wizard will open. In its window, select the volume (disk) to be expanded and the amount of space to be added, click next and voila - after a short wait we get drive C with an increased amount of memory. Well, after such manipulations with hard drive Be sure to restart the computer.



The second method should not scare you; in fact, it is even simpler. The only thing you first need to download and install the Acronis Disk Director program on your computer. I recommend it, as it has great functionality, allows you to make backup copies of the OS and hard drives and many other operations with disks. But more on that later. In the meantime, we are interested in enlarging the C drive at the expense of the D drive.


After installation, we launch the program, a fairly clear program interface opens, which displays all the disks of our PC. To enlarge drive C, click on it and select in “Operations” - Resize volume. After that, in the new window that opens, check the boxes next to the items - Add unallocated space to volume and Take free space from other disks. In the window with percentages, we select how much space we want to borrow from other drives. After all the changes, click OK. After this, as in the first case, the system will ask you to reboot for the changes to take effect.


In both cases, you will get the same result and will no longer worry about running out of space on your drives.

I hope my article was useful to you and will help you when you need it!

If the operating system does not have enough memory, it’s time to think about how to increase the size of the disk (C:). Over time, the OS “grows” - new programs appear in it, updates are downloaded. There is less and less free space on the partition, even if you install all the utilities on another volume. You can clean your system disk of junk files or change its size. And you don’t need to format your hard drive or reinstall Windows to do this.

The characteristics of the HDD itself do not change. You are only redistributing existing resources between logical drives. Physical memory remains the same. If you want to expand it, you will have to purchase a new hard drive.

You should not expand the partition if there is still free space on it. If something goes wrong when resizing, you will lose all your data.

During operation, unnecessary information “settles” in the system. These are files left over from deleted applications, outdated cache, registry entries that lead nowhere and do not relate to anything. Separated from each other, they don't weigh that much. But in total they clog up the system and take up a large amount of memory. You can clean the OS of garbage and free up space for Windows needs.

  • Right-click on the disk icon.
  • “Properties” item.
  • General tab.
  • Clean button.

Click on "Cleanup"

  • Check the boxes next to the required items. It's better to delete "Temporary Files". You can also erase “Thumbnails” - these are previews (“thumbnails”) of images and videos. With them you see not an ordinary icon, but a picture or frame. But the cache may store thumbnails of drawings that you no longer need. Therefore, feel free to erase all the previews if they take up extra space. As soon as you open a folder with drawings or photos, new thumbnails for the icons will be loaded into the cache.

Place a checkmark next to the required files

  • You can also use junk removal programs. For example, CCleaner is suitable.

And a few more tips:

  • Do not install resource-intensive programs on the system disk. Use other sections to download games, editors, and multimedia programs.
  • Do not put videos, photos, archives in subdirectories (C:). Transfer your personal information to another location.
  • Don't clutter your desktop with shortcuts and folders.

Cleaning the OS does not change the size system disk. But this will increase the amount of data that can theoretically fit on it.

In what cases is it necessary to expand the disk?

If Windows has enough resources to run, you don't need to touch anything. Manual expansion logical partitions are associated with certain risks. If you do something wrong, the system will stop booting. Change the size of the system directory only as a last resort. For example:

  • Windows was initially allocated little space. When “slicing” the volumes, they did not calculate how much memory was needed for stable operation.
  • You cleaned the OS of garbage, deleted unnecessary data, moved your files to another partition, but this did not help. The free space in the system partition fills up too quickly, because various updates, extensions, and add-ons are constantly installed.

Computer management

Here's how to increase memory on C drive without third-party utilities:

  • Right-click on the “My Computer” icon.
  • Item "Management". To open this menu, you need administrator rights.
  • Expand the "Storage Devices" list. It's on the left side of the window.
  • Select the "Disk Management" sub-item.


Find and launch Disk Management

  • Right-click on the system partition.
  • You need the "Expand volume" line to increase the size. If this item is not active, then additional volume is needed.
  • To get it, right-click on any other drive that has free space.
  • Select Shrink Volume.
  • Specify the number of megabytes you want to “transfer” to (C:).
  • Confirm the action and wait until the system shrinks the partition.
  • Now you have unallocated memory. And the “Extend volume” option will be active.
  • The computer may restart several times to complete the operation. Do not interrupt the process or turn off the PC.

Do not touch the System Reserved object. Do not change drive labels (“letters”) or paths to them. Do not do it active section, which does not have an OS installed.

Third party utilities

You can change the size of volumes using special programs. They are called "Partition Managers". They have a simple interface. You don't need any special skills to work with them. But you still need to use such utilities carefully. If you do something wrong, you can actually remove all volumes and erase data.

Almost all of these applications have a similar interface. Therefore, for other programs the algorithm of actions will be the same.


Acronis Disk Director window

Here's how to increase disk space (C:) using Acronis Disk Director:

  1. Install this utility. You can download it from the official Acronis website. It's paid, but a demo version is available to download. There are also “hacked” versions of the program on the World Wide Web.
  2. Launch it. A window will open with a list of logical partitions.
  3. Right-click on the volume whose volume you want to increase.
  4. “Resize” item. He's first on the list context menu.
  5. Check the “Add unallocated space” and “Take from other volumes” checkboxes.
  6. In the “Leave free space on volume (%)” counter, indicate what percentage of memory to leave in the partition. This value depends on general parameters hard drive and local disk that you are compressing. If you set it to 80%, 20% of the volume (D:) will be added to the system partition. Don't overdo it. You should not “drag” all free resources to (C:). This way you will have nowhere to put your personal data.
  7. In the “Size” field, specify the desired size of the system volume.
  8. Click OK. The settings window will close.
  9. In the program itself, click on “Apply pending operations”.
  10. The utility will prepare and check everything. After you click Continue, your computer will restart (possibly more than once). During system startup, disk space will be redistributed. Do not turn off the PC, do not unplug the cord from the outlet, otherwise you will lose data from the partitions.

After the download is complete, you will see that the volume (C:) has increased.

You can also do this: free up space by compressing one volume and add this “orphan” memory to another.

Aomei Partition Assistant

Here's how to increase disk size (C:) using Aomei Partition Assistant:

  • Download and install the program. You can find it at aomeitech.com. Open the main page of the resource global network and go to the "DOWNLOAD" tab. The standard (“Standard”) license of the utility is distributed free of charge.
  • Launch it. A list of available volumes will open.
  • First, you need to shrink the drive (D:) to free up space. Right-click on it and select “Edit”.


  • Reduce the volume of the section. To do this, enter a numeric value or move the slider that shows how much memory is allocated.


Resizing disk (C:)

  • Now change the drive (C:) exactly the same as (D:). Just don't shrink, but expand the volume.
  • After setting up and allocating memory, you need to click the “Apply” button in the main window of the utility.
  • The computer may restart several times. Don't turn it off, even if the process takes a while.

The program does not have Russian (although you can find versions with amateur translations online). But it’s just as easy to use as previous utilities. It works on both Windows and Linux.


MiniTool Partition Wizard window

  • Download the application from partitionwizard.com, install and run. A list of volumes appears.
  • Free up memory first. Right-click on the drive (D:) (or any other one if it is not reserved by the system).
  • “Move/Resize” item. A window for changing the volume will open.
  • You can manually enter values ​​or adjust the slider.


  • In the “Unallocated Space After” field, indicate what size of the disk you want to end up with (if you shrink the volume, the number of megabytes will be less than the original).
  • Confirm the action.
  • Do the same for the (C:) drive. Allocate free memory to it.
  • The slider should be adjacent to the left side of the window. If there is a “space” between it and the border, problems will arise with loading the OS.
  • Confirm again.
  • Click the "Apply" button. It is located in the upper left corner of the main application window.
  • Wait while the program redistributes resources between volumes. Don't turn off your computer.

How to change disk size when installing Windows?

If you install or reinstall Windows, you can change the size of the system disk directly during initialization. But this will not save system parameters, design, programs and other data. Better back up your important information.

  • Start Windows from a CD or flash drive.
  • When it comes to choosing the installation type, click on “Full installation". A list of sections will open.


Select " Full installation»

  • Don't touch volumes you know nothing about. Most likely, there is important system data there. Work only with people you know (C:) and (D:).
  • Select the one whose size you want to change.
  • Click on the Disk Setup link.
  • And then click on the “Expand” button.
  • To use it, you must have unallocated memory. To create it, you can delete one of the partitions that does not belong to the OS. Then add required volume to the system disk. And from the remaining resources to form a new top.

The option will be relevant:

  • If this is your first Windows installation.
  • If you decide to “start over” and format the hard drive.

In the first case, there is no unrecoverable data on the computer, in the second, there shouldn’t be any.

You've learned several ways to make your drive (C:) larger. But don't do it without a reason. If the system needs free space for virtualization, paging file, storage of backups and recovery points, then it makes sense to change the size of the main volume. But if everything works fine, and there is still enough memory in the partition, it is better not to touch anything.

What partition manager would you recommend?

If the operating system is already installed. Friends, this article can be successfully applied if you have the operating system Windows XP, Windows 7.

  • In this article we will apply to you paid program Acronis Disk Director, but the same operation can be done by free programs: and, in the end, you can choose what you work with. By the way, if you have the Windows 7 operating system installed, you can do this without resorting to any programs.

So here we will use Acronis Disk Director. Use this program if you need to divide your hard drive into several partitions or if you need to change the size of a partition. You can also use this program to find and restore a deleted partition. There are a lot of articles on our website that describe working with this program, you can find them. In our case, we incorrectly partitioned the hard drive when installing the operating system.

  • Acronis Disk Director can be installed directly into Windows, but many users work from the program's boot disk, so there are fewer errors. can be created in Acronis Disk Director itself.
  • Acronis Disk Director is a disk partition manager, which means that when working with the program there is a risk of accidentally deleting all partitions on your hard drive if you do something wrong.
    Therefore, before working with Acronis Disk Director, I recommend making a backup of all partitions of your hard drive. It's very simple. Any user, regardless of experience with a computer, simply must be able to create a backup of the operating system and, if necessary, deploy it back.
    These detailed articles will help you master indispensable operating system recovery tools. These tools will help you restore your operating system in any case.

It so happened that when working at a computer, the user got used to having a hard drive divided into two partitions D:/ and C:/. Where on one the folder with the system is stored, and on the other they save various media files, such as photos, music, films, etc. But, sooner or later, everyone who works in the operating room Windows system I've probably come across a situation where it was necessary to increase the size of drive C at the expense of drive D, due to lack of free space.

Usually, this disk fills up due to the fact that there is an overabundance of various programs and games installed on the computer. Also, this place fills at incredible speed if the user saves everything possible files only on the desktop. Another reason for filling up free space is temporary files from the Internet and . As a result, due to lack of space on the system partition, you will not be able to download anything from the Internet and will not even be able to run more than one program.

A few sentences below you will find detailed instructions About, how to enlarge drive C by using various ways, starting from third party software and ending with the LiveCD, which I think many people already know about with . Of course, we will not forget to consider increasing the size of the C drive using the standard Windows utilities, entitled "".

Before we get started, I want to note some nuances.

  • We will increase the size of drive C at the expense of drive D. Therefore, make sure that you have enough free space on the local drive D:/;
  • Unfortunately, you can increase the space on drive C using standard program disk management will not be possible without data loss, so be extremely careful so that you don’t have to do it manually later;
  • All the tips that I will describe below apply to absolutely all major operating systems, Windows families (7/8/10);

So we free up disk space from which we will bite off a piece and proceed to the practical part of the instructions on how to enlarge drive C at the expense of D.

Increase disk space with Aomei Partition Assistant utility

First we will use the program, which is distributed in free form and will help us increase the size of the C drive, directly from the Windows working environment. But, before you use it, of course, you need to download and install it on your computer. There is nothing to explain here, I think you will cope with this with a bang.

The main thing is that during the download process, do not forget to change the installed language to Russian.

Having launched the program, its interface should open in front of you, with various windows which will display full information about the hard drive and all the partitions into which it is divided.

So, since we came here with the goal of increasing the size of disk C, taking the free space from D, we perform the following steps in order.


If you simply resize the disks and don't press the apply button at the end, you won't get the expected result. After completion, the computer will reboot several times and you will receive the additional space on the system disk that you specified earlier.

We increase the space on the system disk using Disk Director.

The next option is also not bad, but it is not entirely convenient, in that to implement it we will have to boot from it later.

You might ask, if it is so complex, why am I showing it? Hmm, there are actually a lot of reasons, for example, you need to increase the size of drive C at the expense of drive D, but when using various programs, a message constantly appears that the system cannot lock the drive to complete the operation. So, it is precisely in such cases that a LiveCD with the Disk Director program helps us out.

So, for those who don’t yet have such a disk, you can download the one that I use: Link. Next, just record it on any disc, as a simple image and .

In the loaded LiveCD, find the Disk Director icon on the desktop and launch the program. An interface will appear that is very similar to the working environment of the program we discussed just above.

To increase the size of drive C, perform the following steps:

  1. IN top panel Click on this icon, which will launch a window to increase free disk space;
  2. In the dialog box that appears, select the partition to which we want to add free space and click “ Further»;
  3. In the next step, we will need to select a partition through which we will add free space;
  4. Next, the wizard to increase free space will ask you to use the slider to indicate the size of the partition to be expanded, in our case it is drive C. Having moved the slider as you need, click “ Further", to continue;
  5. Before starting the process, the program will definitely show you the structure of the newly created partitions and ask you to press the “ Complete»;
  6. Now, to apply all changes, click on the checkbox;
  7. A list of operations that have been scheduled appears. Having familiarized yourself with them, click on “” to begin performing all the processes to increase the size of drive C;
  8. The transformation will take a few minutes, although the procedure itself may take up to an hour depending on the size hard drive;
  9. After the program has finished running, reboot the computer and check whether Disk Director has completed its task;

Maybe this method is not the most convenient due to the fact that you need to create new disk, but it is not more effective for me than others, and will always help out in situations where programs from the system’s working environment simply cannot cope.

Increase space on drive C using Disk Management

And finally, as I promised, let’s look at how you can increase drive C at the expense of drive D using Windows’ own resources. Those who decided to use this method, I hope you haven’t forgotten that it has one rather serious drawback: when the partition is enlarged, your personal data will be deleted from the disk “ D" Therefore, I recommend using this option only on new machines and clean hard drives.

If you still intend to use this particular method, then call up the window “ Execute» by clicking « Windows+R" and execute the command there .

The window of the utility we need will open, which will display all the drives that are connected to the computer. There, separately, you will see your sections C and D, and several hidden ones boot sectors, by the way, which I recommend not to touch under any circumstances, so that you don’t have to restore the system later.

Now, having selected the section with the letter D, right-click on it and click “”. Performing this action will delete both the disk itself and k and all the data stored on it, therefore, do not forget to save it somewhere else, for example on a flash drive.

In the next step, go to drive C and call the context menu in the same way, but this time select “ Expand volume..." A window will appear where you will need to specify the size of the free space to be added. All the space that we freed up by deleting drive D will immediately be displayed, but since we don’t want to take everything, we only indicate a small part of the number we need, for example 4000MB.

Attention!!! If the disk you want to enlarge has a button “ Extend volume", I recommend using the first or second option.

By increasing the size of disk C at the expense of D, we return our donor back to normal. To do this, right-click on the unallocated space and select the first line “ Create a simple volume"and then follow the instructions, which he recommends utility. The volume letter will be formatted and assigned, after which you will be able to use it as before.

In this article I did not try to show you different programs that do the same thing, here I wanted to tell you about three methods that can help you in completely different situations. For example, you can use the first option during normal system operation, the second in case of some kind of breakdown, and the third in the case of a new computer, you don’t have to download anything, but can quickly do everything using “Disk Management”, spending only 5 minutes.

How to enlarge drive C at the expense of drive D in Windows 7, 8.1, 10

Good afternoon. Most people buy computers from finished assembly, that is, the system is installed on it, all the components and components of the computer are configured, the BIOS is configured, and so on. This is, of course, good. But, sellers very often sell PCs, HDD which has only one section.

Should the hard drive be partitioned?

In other words, there is a system on one partition, and on this same partition people download movies, install programs, games, etc. Then, wanting to learn to better understand computers and their programs, people look at installed programs, files, and so on.

Some of them are deleted, some are edited, etc. But, since Windows is installed on the same partition, it is quite difficult for a person to distinguish between the program that he himself installed and where the system software is.

But, if the user accidentally deletes one of the system files, then it’s very possible that the computer simply won’t start. Hence, it is very bad and inconvenient when the hard drive is not divided into sections. Therefore, when you buy a computer, ask the seller to have the hard drive divided into a couple (or three) partitions. At least two. Although, in my opinion, three is more convenient. On one the system is installed, on the other there is working software, on the third there are various videos and games.

In my opinion, this is the most convenient option. But, if you already bought a computer with a single partition, it doesn’t matter! The Winchester can be broken down into three parts (or more if you like). Of course, this can be done during OS installation.

But this is not very convenient, especially if your OS is functioning perfectly. And I don’t want to bother with reinstalling the system. In this case, all that remains is to divide the hard drive into partitions with a working system.

This is quite possible, as strange as it may seem to many users. There are a number of programs that can partition a disk. But the most convenient of them, in my opinion, is Acronis.

Acronis Disk Director 12 description

This program specially designed to work with hard drives. She can quite professionally divide your hard drive into parts, and select a specific size for each section. You can also connect several sections together if you have a lot of them. Among other things, Acronis gives us the opportunity to move or copy the system to any disk partition, and even to another hard drive.

It is very comfortable. For example, you bought new computer and want to copy the system from the old one system unit on new. To do this, you simply remove the hard drive from the new system unit of the new computer, insert it into the old one, and copy the system. You can select the Move command. But, there is a threat that something will go wrong and you will lose the system. If you copy the system, then if there is a problem, you simply start copying the system again.

How to increase the size of the Windows system disk

In addition, it often happens that your system partition is small. For example, only 40 GB. It would seem like a decent size, but by modern standards it’s not much! I would even say - not enough (especially during latest updates Windows 10, which took up a lot of space).

Since modern programs have a decent weight, over time, depending on their number, and on constant updates, the volume of disk C increases greatly.

What should be done in this case? The most reasonable thing is to increase its size. And, better yet, in abundance. I advise you to set the system disk size to at least 100 GB, and preferably 120 GB, as I will do. For this, we need Acronis Disk. This program is paid. In general, its cost, considering all its functions (and there are a lot of them), is low. In addition, it has a Demo version with limited features.

Download Acronis Disk Director 12 for free from the official website (demo version). Install the program. I recommend installing Acronis on drive C, because... We will work with disk D (we will take some space from it). After installing the program, the Acronis window opens.

Cut off some volume from drive D

From this window we see how many partitions we have and how much space they occupy from the hard drive. So, our task is to increase the system partition. It has a capacity of 88.48 GB. The D drive has 360.3 GB. To increase the system disk, we must first cut off a small part from another disk, in particular from D, and add it to the system one.

Therefore, before the operation of separating part of the D drive, I recommend the most important information copy from this disk to another disk (just in case). Then, the disk needs to be defragmented. The best option is if drive D is completely free.

To do this, we select drive D, and with the right mouse button select “Resize volume” from the context menu.

In the new window we see how much is on it occupied space, and how much is free. In disk space, brown color indicates the space occupied by information. Free space is shown in yellow. Then, we use the mouse to grab the disk strip by the left side and drag it to the right, up to about 30 GB. Please note that the disk capacity is currently 360.3 GB.

After dragging and dropping, the volume became 330 GB. At the same time, in the “Unallocated space in front of the volume” column, we have the number 30.29 GB. Also, to change the volume size, you can simply enter 30 GB in the “Unallocated space in front of volume” column. Please note that in the lower menu that shows our disks, a new disk has been created called “Unallocated Space”. Click OK.

And nothing happens to us because we didn’t click “Apply pending operations” at the top of the menu. Let's click on this command.

The “Pending Operations” window appears. Where we also learn that a reboot will be performed. Click “Continue”.

You must confirm the reboot. We agree.

After the reboot, turn on Acronis Disk Director 12.

How to Attach Unallocated Space to Drive C

So, having turned on Disk Director 12, note that now our D drive is 330 GB, and next to it there is unallocated space of 30.29 GB. Right-click on drive C and select “Resize Volume”.

A window appears where we see that so far our C drive occupies 88.48 GB. This is followed by unallocated space of 30.29 GB. So, we take the right edge of the strip, and with the mouse we drag out the space of drive C to cover the entire period of unallocated space. Or, in the “Unallocated space after volume” column, you can simply enter 0 GB (this will even be better). Next, be sure to check the box next to the “Add unallocated space to volume” command.

Click OK. After that, click “Apply pending operations”. The OS tells us that a reboot is required. We agree. Click OK.

In the next window, click “Continue”.

We are recording transactions

After rebooting, open Acronis and look at the program window. We see that the system disk now takes up 118 GB, and disk D 330 GB. That's what we needed to do. Now the system disk has a decent size, and you can install small programs directly on it (I still recommend installing large ones on another partition of the hard drive).

How to partition a hard drive in Windows 10 if there is only one partition

Your situation may be different. For example, you installed a system, you started working with it, installing programs, downloading music, movies, games, etc. Then, you realized that your friends’ hard drives have several sizes, but your store only installed one large section. What can be done in this case? How to split a disk into parts?

You can split the disk into parts while reinstalling the system, but then you will completely lose all information from the disk. First of all, you need to defragment the disk. Transfer special information to removable media.

Next, launch Disk Director 12. Select “Resize volume” (I will show it on my C drive). Then, take the right edge of our disk and drag it closer to the center. Let me remind you that the dark green stripe is space on the disk occupied by information. Light green, free disk space. Set OK.

If you don't like the volume letter, you can change it. Also, it is advisable to format the new disk in NTFS format. We select the cluster size as 4096 bytes.

Other program features

In addition, Acronis can move volumes, merge volumes, split volumes, change the cluster size, format, and defragment the desired partition. Also, she has interesting feature"Check".

That is, if you select this command and in the new window check the boxes “Fix found errors” and “Repair bad sectors”, the program will begin to scan and disinfect system files.

This program function works better than the built-in one, which fixes system errors.

Conclusion: Acronis Disk Director 12 is one of best programs to increase the capacity of the local drive C. combining these partitions, adding capacity to the system drive. It has a convenient design, Russian language, is easy to use and has many others additional functions. Even a beginner can handle it. Good luck!

PS Three years after the article, I rolled back the system using . The backup was made before the disk was enlarged. So, during the rollback, the system returned to its previous state. Including drive C. That is, its volume was again 88.6 GB. A disk with unallocated space has formed next to it. I used the Acronis program again.

The disk was restored to its previous size quickly and efficiently. Why am I saying this? Moreover, if you restore the system from backup copy, most likely the disk will shrink again. But, Disk Director 12 will return the previous size without much effort!
