When new 7-Zip creates multivolume archive, 7-Zip keeps in open state only volumes that still can be changed.Some changes and optimizations in WIM creation code.It can increase compression ratio for executable files larger than 64 MiB. Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB.Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files. ARM64 filter for ARM64 executable files.BCJ or BCJ2 filter for x86 executable files,.ARM64 filter can increase compression ratio for data containing executable files compiled for ARM64 (AArch64) architecture.Īlso 7-Zip now parses executable files (that have exe and dll filename extensions) before compressing, and it selects appropriate filter for each parsed file: 7-Zip now can use new ARM64 filter for compression to 7z and xz archives.The page “Language” in 7-Zip’s menu Tools/Options now shows information about selected translation, including the number of translated lines.Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM.Self-extracting capability for 7z format.

Strong AES-256 encryption in 7z and ZIP formats.For ZIP and GZIP formats, the provided compression ratio is 2-10 % better than the ratio provided by PKZip and WinZip.High compression ratio in new 7z format with LZMA compression and LZMA2 compression.This file archiver works on all Windows operating systems, from Windows NT to 10 (32-bit and 64-bit). And it compresses to zip format 2-10% better than most of other zip compatible programs.ħ-Zip is free software, developed by Igor Pavlov and distributed under the GNU LGPL license. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. It also features integration with the Windows shell environment.Ĭompression ratio results are very dependent upon the data used for the tests. It operates either as a command line program or with a graphical user interface. 7-Zip is an open source file archiver with the high compression ratio predominantly for the Microsoft Windows operating system.
