WinRAR is an archive manager for backing up data and reducing the size of e-mail attachments. Decompress files downloaded from the Internet and create new archives in RAR and ZIP file format. Support is provided for RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z, and 7-Zip file formats. WinRAR recognises and selects the best compression method for decompressing multi-media files; the compression algorithm compresses multi-media files, executables and object libraries. Split archives into separate volumes in order to save them on several disks. 128-bit password encryption and authenticated signature technology is included.
