7-Zip 24.09 – 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).

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.

Changes in 7-Zip 24.08 (2024-08-12):

• The bug in version 24.00-24.07 was fixed:
  For creating a zip archive: The app could write extra zero bytes after the end of the archive, if a file included to archive cannot be compressed to a size smaller than original.
  The created zip archive is correct except for the useless zero bytes after the end of the archive.
  When unpacking such a zip archive, the app displays a warning:
  “WARNING: There are data after the end of archive”.
• The bug was fixed: there was a leak of GDI objects (internal resources in Windows) in “Confirm File Replace” window, causing problems after 1600 displays of “Confirm File Replace” window from same running 7-Zip process.
• Some optimizations for displaying file icons in app File Manager and in “Confirm File Replace” window.
• Some bugs were fixed.
