WinRAR is a shareware file archiver and data compression utility developed by Eugene Roshal, and first released around 1995. It is one of the few applications that is able to create RAR archives naively, because the encoding method is held to be proprietary.
WinRAR supports the following features:
- Complete support for RAR (WinRAR native conversion format) and ZIP archives, and unpacking of ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, EXE, 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, 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.
