7-zip File Archiver

Ryan Kulla - January 29, 2007

7-Zip is an open-source file archiver with high compression ratio. It can compress your files using a variety of methods, such as 7z, ZIP, GZIP, BZIP2 and TAR. It can also extract RAR, CAB, ISO, ARJ, LZH, CHM, Z, CPIO and NSIS archives.

7zip_sshot.JPGLike other file archives you may be used to, 7-zip can integrate into the windows shell and it also has a command-line version. 7-ZIP also offers some advantages over other windows based archive programs such as winzip and winrar:
Open-source – You can read and modify the program source code.

  • Cross-platform – You can run 7-zip on any modern operating system (Windows, Linux, OS X, and so on)
  • No registration – There are no annoying splash screens or nagging registration pop-ups
  • Provides a compression ratio that is 2-10% better than PKZIP and WINZIP provide for ZIP and GZIP archives.

Note that you can register 7-zip if you want to support it by clicking Help->About 7-Zip->register in the 7-Zip File manager but it’s not a requirement and it will never bug you to.

There are two basic ways you can associate certain file types with 7-zip. The easiest way is to open up the 7-zip file manager and choose Tools->Options and in the System tab choose the file extensions you want to associate with 7-zip. This will make it so files ending in those extensions are automatically opened in the 7-Zip file manager for extraction. If you choose to add the associations manually by the standard MS Windows way of right-clicking on a file, choosing “open with”, selecting the “always open files of this type with this program” and then browse for the 7-zip program then make sure you select C:\Program Files\7-Zip\7zFM.exe. There are two other binaries in the 7-Zip installation folder that could confuse you and they are called 7z.exe and 7zG.exe; so make sure to use 7zFM.exe (FM means File Manager)

It is possible that 7-Zip can handle all your file archiving needs but you may run into some files that were compressed using Winzip and they won’t always be compatible with 7-Zip. I personally haven’t came across this issue but just be aware of it.

To extract all the files of an archive first click Edit->Select All and then click the ‘Extract’ Button (As shown in the included screenshot)

    7-zip is by far the best zip tool I’ve ever enocountered and I will never use anything else. It’s so versatile and the fact that it can open and archive almost any fileformat (rar, zip, etc etc) makes it the best I’ve found. I even think it’s free or at least very cheap. I hardly paid much for it… đŸ™‚

    @Thor: Totally agree with you. Especially for zipping or unzipping huge amount of data like gigabites of music or pictures to be sent over the internet I find 7ZIP much faster than i.e winzip. Great tool.
