RAR For OS/2 - Version 2.50 RAR rivals PKZIP and ARJ in the number of options available and compression it will achieve. It can be used from the command line or through a built- in menu interface. It features archive adding, extracting, deleting, freshening, and testing, plus password protection, six levels of compression, recursive subdirectories, and self- extracting archives. You can move files out of the source directory into an archive and create volume archives that span multiple floppies. The menu/file manager will also work with ZIP, ARJ, and LZH files (appropriate archivers required).
