7zip

A Windows utility for archiving files in its native 7Z, as well as ZIP, TAR and WIM (Windows image) compression formats. It can also decompress a large number of formats. 7Z archives can be up to 10% smaller than files compressed with other methods, and users have a choice of several algorithms and compression adjustments. Although there is a command line version for Linux/Unix, the Windows version provides a graphical interface with optional encryption. See archive program.



archive program

Software that compresses multiple files and folders into a single file (the "archive"). If a folder or a hierarchy of folders is compressed, the file/folder relationship is maintained within the archived file, and it is restored when the archive is decompressed back to its original state. Although there are numerous compression formats, many archive programs (archivers) support the very popular ZIP format. See archive, archive formats, ZIP file and data compression.
