PeaZip is an OS-portable archiver tool (released for Windows and Linux); it supports it's native Pea archive format (featuring compression, splitting and flexible encryption and integrity check schemes) and other mainstream formats, with especial focus on handling open formats. Full support: 001 (raw file split/join), 7z, 7zip sfx, Bzip2, Gzip, Pea, Tar, Zip; Browse/extract-only support: Z.

PeaZip doesn't follow the Explorer-like interface paradigm; the interface is more similar to a CD/DVD-burner application, allowing the user to: - save and restore layout of archives (input files and folders list) to speed up definition of archiving and backup operations; - save job definition (as plain text, to be used in any script language).

The interface is fully skinnable (skins can be customised and saved as plain text to be re-edited as freely as possible) and uses customisable transparency. The program doesn't need to be installed/unistalled, it can run from any path (even remote; a writeable path is recommended), however Windows version is released both as a standalone binary and as a fully automated installer/uninstaller package, allowing tight system integration to use PeaZip right from Explorer.
