7-Zip 25.00 – Free File Archiver

7-Zip is an open source file archiver with the high compression ratio predominantly for the Microsoft Windows operating system.

It operates either as a command line program or with a graphical user interface. It also features integration with the Windows shell environment.

Compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And it compresses to zip format 2-10% better than most of other zip compatible programs.

7-Zip is free software, developed by Igor Pavlov and distributed under the GNU LGPL license. This file archiver works on all Windows operating systems, from Windows NT to 10 (32-bit and 64-bit).

The main features of 7-Zip:

• Self-extracting capability for 7z format
• Integration with Windows Shell
• Powerful File Manager
• Powerful command line version
• Plugin for FAR Manager

Changes in 7-Zip 25.00 (2025-07-05):

• This app for Windows can now use more than 64 CPU threads for compression
  to zip/7z/xz archives and for the app benchmark. If there are more than one processor group in Windows (on systems with more than 64 cpu threads), the app distributes running CPU threads across different processor groups.
• bzip2 compression speed was increased by 15-40%.
• deflate (zip/gz) compression speed was increased by 1-3%.
• improved support for zip, cpio and fat archives.
• fixed some bugs and vulnerabilities.

Changes in 7-Zip 24.09 (2024-11-30):

• The default dictionary size values for LZMA/LZMA2 compression methods were increased:dictionary size compression level

v24.08 v24.09 v24.09
32-bit 64-bit
8 MB 16 MB 16 MB -mx4
16 MB 32 MB 32 MB -mx5 : Normal
32 MB 64 MB 64 MB -mx6
32 MB 64 MB 128 MB -mx7 : Maximum
64 MB 64 MB 256 MB -mx8
64 MB 64 MB 256 MB -mx9 : Ultra

• The default dictionary size values for 32-bit versions of LZMA/LZMA2 don’t exceed 64 MB.
• 7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5.
• APM and HFS support was improved.
• If an archive update operation uses a temporary archive folder and the archive is moved to the destination folder, 7-Zip shows the progress of moving the archive file, as this operation can take a long time if the archive is large.
• The bug was fixed: 7-Zip File Manager didn’t propagate Zone.Identifier stream for extracted files from nested archives (if there is open archive inside another open archive).
• Some bugs were fixed.
