WinRAR (a.k.a. RAR) is a shareware file archiver and data compression utility developed by Eugene Roshal. It is one of the few applications that is able to create RAR archives natively, as the encoding method is held to be proprietary.


WinRAR supports the following features:

  • Complete support for RAR and ZIP archives, and unpacking of ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7z and Z archives. Future versions of WinRAR are planned to include 7z creation.
  • The ability to create self-extracting and multi-volume (split) archives.
  • Data redundancy is provided via recovery records and recovery volumes, even allowing reconstruction of damaged archives.
  • Support for advanced NTFS file system options and Unicode in file names.
  • Optional archive encryption using AES (Advanced Encryption Standard) with a 128-bit key.
