The two have the same syntax and options, differing only in that 7za is a self-contained app compiled only for use with 7z and the essential Unix formats (tar, gzip, bzip2, etc.), while 7z uses a plugin architecture that allows it to support many additional compression formats. For Linux users, the project links to a command-line client package named p7zip that provides two executables, 7z and 7za. The 7-Zip app is open source, but remains Windows-only. The combination of those two features had made them popular choices for online distribution of extremely large files such as ISO images. They also support splitting large archives into multiple small volumes for easier mobility and error recovery. The 7-Zip Windows app and a 7z software development kit are available under the LGPL.īoth formats purport to achieve better compression ratios for common data types than older algorithms. Its native format is 7z, which uses a modern offshoot of the LZ77 compression algorithm.

Roshal sells a commercial utility for Windows called WinRAR, but also offers uncompress-only clients for a number of operating systems at no charge.ħ-Zip is a Windows application designed to handle as many compression formats as possible.

#UNRARX RARLAB ARCHIVE#

RAR - short for Roshal Archive - is a proprietary file compression format developed by Eugene Roshal. But with the right software, you can handle these compressed files without much trouble.įirst, a little background.

The RAR and 7-Zip file compression formats originated on Windows, so support for them on Linux is not as automatic as it is for old Unix holdovers like Gzip and TAR.
