PeaZip Portable 4.9 is the easy to use PeaZip file archiver packaged as a portable app, so you can take your file archiver with you and work with your compressed 7z, ZIP, GZIP, BZIP2, TAR, RAR files and more on the go.

PeaZip can extract most of archive formats both from Windows and Unix worlds: currently 134 file extensions are supported ranging from mainstream 7Z, RAR, TAR and ZIP to experimental ones like PAQ/LPAQ family, currently the most powerful compressor available.
