7-Zip is a free software/open source file archiver designed originally for Microsoft Windows. 7-Zip operates primarily with the 7z archive format, as well as being able to read and write to several other archive formats. In operation a user can use the command line, graphical user interface or Windows shell integration. 7-Zip began in 2000 and is actively developed by Igor Pavlov. It is related to a cross-platform port, p7zip.

Compression ratio

We compared 7-Zip with some of the leading archivers.

– 7-Zip now can update solid .7z archives.
– 7-Zip now supports LZMA2 compression method.
– 7-Zip now supports XZ archives.
– 7-Zip now can unpack NTFS, FAT, VHD and MBR archives.
– 7-Zip now can unpack GZip, BZip2, LZMA, XZ and TAR archives from stdin.
– 7-Zip now can open/copy/compress disk images (like \\.\c:) from \\.\ folder.
– 7-Zip File Manager now doesn’t use temp files to open nested archives
stored without compression.
– New -scrc switch to calculate total CRC-32 during extracting / testing.
– New -scc{WIN|DOS|UTF-8} switch to specify charset for console input/output (default = DOS).
– Some bugs were fixed.

What’s new in 7-Zip 24.09:

• 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.
