7zip

7-Zip is a file archiver with a high compression ratio.

The main features of 7-Zip are:

• High compression ratio in 7z format with LZMA and LZMA2 compression
• Supported formats:
• Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
• Unpacking only: APFS, 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, VHDX, VMDK, WIM, XAR and Z.
• For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
• Strong AES-256 encryption in 7z and ZIP formats
• Self-extracting capability for 7z format
• Integration with Windows Shell
• Powerful File Manager
• Powerful command line version
• Plugin for FAR Manager
• Localizations for 87 languages

What is Being Tested?

7zip is used to measure performance in terms of compressionTime, and ratio of compressed size and original size. Below are the metrics measured by 7zip Workload.

Name	Unit
Compressed size and Original size ratio	-
CompressionTime	seconds
