5.0 – supported by WinRAR 5.0 and later. Changes in this version: Maximum compression dictionary size increased to 1 GB (default for WinRAR 5.x is 32 MB and 4 MB for WinRAR 4.x). Maximum path length for files in RAR and ZIP archives is increased up to 2048 characters. Support for Unicode file names stored in UTF-8 format.
The RAR 5 format improves multi-core processor utilization, and adds a larger dictionary size of up to 1 GiB with 64-bit WinRAR. Special optional compression algorithms optimized for RGB bitmaps, raw audio files, Itanium executables, and plain text, which were supported by earlier versions, are supported only in the older RAR format, not RAR5.

Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [ 1] By contrast, lossy compression permits reconstruction only of an approximation ...
Programs like bzip2, gzip, tar, zip usually come with systems that contain Ark; writing in .rar format requires a commercial program.[ 47] ^ a b c supports the formats as stream compression of other archive format and can create compressed format like tar.bz2 or iso.xz but cannot create an archive in these formats.
Preferred compression algorithm is a combination of RLE and 12-bit LZW. Archives can be manipulated with the command-line NuLib tool, or the Windows-based CiderPress. .sit application/x-stuffit StuffIt: Originally Classic Mac OS, now multiple Originally Classic Mac OS, now multiple Yes A compression format common on Apple Macintosh computers ...
In computing, solid compression is a method for data compression of multiple files, wherein all the uncompressed files are concatenated and treated as a single data block. Such an archive is called a solid archive. It is used natively in the 7z [1] and RAR [2] formats, as well as indirectly in tar -based formats such as .tar. gz and .tar. bz2.
ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common.
Weissman score. The Weissman score is a performance metric for lossless compression applications. It was developed by Tsachy Weissman, a professor at Stanford University, and Vinith Misra, a graduate student, at the request of producers for HBO's television series Silicon Valley, a television show about a fictional tech start-up working on a ...
