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.

Optional archive encryption using AES (Advanced Encryption Standard) with a 128-bit key.
WinRAR Unplugged is a portable version of WinRAR that does not require installation or create dependencies on the host computer.
[edit]Version history
Below is a summary of version information. Version 2.00 was released on September 6, 1996.
Since version 2.90, the new RAR3 archive format is implemented. The new compressed archives cannot be managed by old versions of WinRAR.
Since version 3.50, WinRAR adds support for interface skins and themes and support Windows XP x64.[6]
Since version 3.60, WinRAR includes a multithreaded version of the compression algorithm, which improves compression speed on systems with multiple, dual-core, or Hyper-threading-enabled CPUs.
Since version 3.70, WinRAR features support for Windows Vista.[7]
Since version 3.80, support for ZIP archives, which contain Unicode file names in UTF-8.[8]
Since version 3.90, WinRAR adds support Windows x64 natively and support Windows 7. Also it enhanced support for multithreading.[9]
Version 4.00 speeds up decompression by up to 30%. Windows 98, Windows Me, and Windows NT are no longer supported; the minimum Windows version required is Windows 2000.[10]
Since version 4.10 WinRAR removes all ZIP limitations now allowing unlimited number of files and archive size. WinRAR now also allows to create multivolume ZIP files. ZIP archives now include Unicode file names.[11]
Since version 4.20 Compression speed in SMP mode has been increased significantly, but this improvement was made at the expense of increased memory usage. ZIP compression now uses SMP as well. The default SMP mode cannot handle text; text compression is significantly worse unless additional switches are used. Also, Windows 2000 compatibility was removed. [12]
