WinRAR is a file archiver and data compression utility by Eugene Roshal. It is arguably one of the two main file archive programs for Windows, along with WinZip. It is one of the few applications that is able to create RAR archives natively, as the encoding method is held to be proprietary.
- Complete support for RAR and ZIP archives, and unpacking of CAB, 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.
