Features of the 7-Zip archiver

When compressing files in 7-Zip, multiple threads are used simultaneously, which significantly speeds up the process. For example, when archiving in zip format, up to eight streams are used simultaneously. That is why this program is ahead of many of its competitors in terms of file archiving speed. For example, on a computer with a single core processor the compression speed is almost identical to WinRAR, and on a dual core processor it is significantly higher than the latter.

An archive is simply a single file that compresses other files to reduce its overall size. If you still sigh when you receive another file in a ZIP, RAR, 7-Zip or any other archive, then this article is for you.

For those who like to watch, I’m posting a video:

The easiest way to extract a ZIP archive

ZIP archives are regular files with the extension ".zip". In fact, you don’t need any programs to simply unzip files from ZIP; everything is already built into Windows Explorer 7/8/10. Just right-click on the file and select “Extract all...” from the menu.

A dialog box will appear where you will need to specify the path to unpack the files, or leave it as default (current folder). As you can see, in the example I have a “Checklist.zip” file with a zipped Word document.

If you leave the “Show extracted files” checkbox enabled, then at the end of the unzipping procedure, another Explorer window will open with a new folder open. Or you can not unpack the files at all, but go into the archive like a regular folder and open the desired file from there.

How to unpack RAR archive

Unfortunately, Explorer cannot work with RAR files. For them you need to install one of the programs that will be discussed. The free 7-Zip program has long proven itself to be simple and free archiver. Can unpack files 7z, zip, rar and others.

Using the program is almost as simple, just right-click on the file and select one of the items from the “7-Zip” submenu:

  • “Unpack” – to open the extraction dialog
  • “Extract here” – to simply extract the files to the current directory
  • “Extract to “Folder Name” - extract files to a folder with the archive name (I recommend)

The simplest are the second and third options, because... do not require any further action. If you select the first option, the following dialog will appear:

Here we can specify our path for the files. If you select the “No paths” option, then all files from the archive will be in one heap, without subfolders. The “Overwrite” parameter is responsible for the mode of overwriting existing files. By default, the program will ask about each such file.

You can extract files not only from the right-click menu. If you double-click on the file, it will open in the 7-Zip program window. To unzip files, simply select them and click the "Extract" button

Alternative free method - Hamster Lite Archiver

I also want to introduce you to one newfangled program Hamster Lite Archiver. It is even simpler, free and has a modern interface. After installing it, new items also appear in the Explorer context menu. To unpack a rar or zip archive, right-click on it and select one of the options:

  • Extract files… - opens a dialog window
  • Extract Here – extracts files into the current folder
  • Extract to “Folder name” - unzip to folder

Although the points context menu in English, the program itself is in Russian. Apparently we haven’t gotten around to translating these points yet, but by the time you read this article the situation may have already improved. The dialogue looks like this:

Universal program WinRAR

The WinRAR program is very widely used for working with RAR archives, I only use it. The program is possible. Look immediately for the Russian version in the list. Installing WinRAR is very easy, just click “Next” all the time. The program is paid, but with a trial period of 40 days. After graduation trial period WinRAR continues to work, but it starts to bother me with a window reminding me about the license every time I start it.

To unpack a RAR file, or any other archive, just right-click on the file and select one of the options:

  • Extract files... - the unpacking dialog will open
  • Extract to current folder – contents will appear in the current folder
  • Extract to “folder name” - unzip the contents into a new folder with the archive name (recommended)

The most simple options this is the second and third. If you select the first option, a dialog will appear in which you can specify the specific path where your files will be placed and a few more parameters:

Update Mode:

  • Extract with file replacement - if the folder already contains the same files as in the archive, then they will be replaced with new ones
  • Extract with file update is the same, but only older files will be replaced
  • Update only existing files - only the update will occur, the remaining files will not be extracted.

The “Overwrite mode” items are responsible for the behavior of the program when replacing existing files.

Using this dialog, you can unpack a damaged or incomplete archive. By default, if a file has an error, it will not be unpacked. If you check the “Leave damaged files on disk” checkbox, then the damaged archive will be partially unpacked. If it is a video or music, then it can be opened. But, of course, the completeness of the resulting file will depend on the degree of damage to the archive.

You can also unpack files from the WinRAR program window. To do this, it is enough to select necessary files and click on any of the buttons: “Extract...” or “Master”.

WinRar will also help you organize a backup of your information.

Please note that after installing any of the listed programs, the standard “Extract...” menu item for ZIP archives may disappear from Windows Explorer.

How to unpack a multi-volume archive

Multi-volume archives are created to split one huge archive into several small ones. In this case, there will be numbers at the end of the file names, for example.z01, .z02, .z03 or part1, part2, part 3 or 001, 002, 003, etc. To unpack such a multi-volume archive you will need ALL the parts, otherwise nothing good will come of it. The unpacking process itself is no different from the usual one.

You just need to unzip the first file from the list in the usual way, and the rest will be picked up automatically.

If, in addition to the numbered parts, there is also a “regular” archive, then it is this file that needs to be unpacked, it is the main one.

Please note that multi-volume ZIP archives created by WinRAR can only be unpacked with the same program! Other programs give an error and even if you crack! And vice versa, WinRAR does not understand multi-volume files created by other programs.

Conclusions:

So, you can extract files from zip, rar, 7z archives using Windows Explorer (ZIP only) or using the free programs 7-Zip and Hamster Lite Archiver, as well as using paid program WinRAR. Choose a method that is convenient for you and use it for your health!

Imagine how grateful your friends will be if you share this information with them in in social networks! By the way, you can also create your own archives using these programs.
