XZ Utils can compress and decompress the xz and lzma file formats. Since the LZMA format has been considered legacy, [2] XZ Utils by default compresses to xz. In most cases, xz achieves higher compression rates than alternatives like zip, [3] gzip and bzip2. Decompression speed is higher than bzip2, but lower than gzip.
MS-DOS/Windows Compression format(s) used by some DOS and Windows install programs. MS-DOS includes expand.exe to decompress its install files. The compressed files are created with a matching compress.exe command. The compression algorithm is LZSS.
Files can be returned to their original state using uncompress. The usual action of uncompress is not merely to create an uncompressed copy of the file, but also to restore the timestamp and other attributes of the compressed file. For files produced by compress on other systems, uncompress supports 9- to 16-bit compression.
The file manager has a toolbar with options to create an archive, extract an archive, test an archive to detect errors, copy, move, and delete files, and open a file properties menu exclusive to 7-Zip. The file manager, by default, displays hidden files because it does not follow Windows Explorer's policies.
With version 8.51 from 22 August 2012, ALZip changed the license so that it can be licensed freely. On the download page of ALZip is a serial number to copy and paste when you start the program, in order to have the license for the software free of charge. [15]
xz: a streaming implementation that contains a gzip-like command line tool, supporting both LZMA and LZMA2 in its xz file format. It made its way into several software of the Unix-like world with its high performance (compared to bzip2 ) and small size (compared to gzip ). [ 2 ]
Arch uses zstd -c -T0 --ultra -20 -; the size of all compressed packages combined increased by 0.8% (compared to xz), the decompression speed is 14 times faster, decompression memory increased by 50 MiB when using multiple threads, and compression memory increased but scales with the number of threads used.
The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program.
