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.
They also offer an optional command-line interface, while Windows itself does not. Windows archivers perform both archiving and compression. Solid compression may or may not be offered, depending on the product: Windows itself does not support it; WinRAR and 7-zip offer it as an option that can be turned on or off.
In 2011, TopTenReviews found that the 7z compression was at least 17% better than ZIP, [18] and 7-Zip's own site has since 2002 reported that while compression ratio results are very dependent upon the data used for the tests, "Usually, 7-Zip compresses to 7z format 30–70% better than to zip format, and 7-Zip compresses to zip format 2–10% ...
The order matters (these operations do not commute), and the latter is solid compression. In Unix, compression and archiving are traditionally separate operations, which allows one to understand this distinction: Compressing individual files and then archiving would be a tar of gzip-compressed files – this is very uncommon.
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.
The latter does not require an external program to decompress the contents of the self-extracting file and can run the operation itself. However, file archivers like WinRAR can still treat a self-extracting file as if it were any other type of compressed file.
