WinRAR is a shareware file archiver and data compression utility. It can create archived files in ZIP or proprietary RAR format, and unpack many archive file formats. WinRAR runs under Microsoft Windows in GUI mode. There are command-line versions, called "RAR" and "UNRAR" (released since autumn of 1993), available for Mac OS X, Linux, FreeBSD, Windows console mode, and MS-DOS.
Starting with version 5, a new archive format, RAR5, is supported, incompatible with the previous one, but also using file extension .RAR. With the introduction of RAR5, the older format is referred to as RAR4. Newer WinRAR versions can still open and create RAR4 archives, but older versions do not support RAR5 archives.
Both the numerous features (authenticity verification, old style extension based arcname.rNN volume names, file comments) are removed from RAR5, and by default RAR5 is slower than RAR4 (default dictionary size for WinRAR v5.x is 32 MB, typically resulting in higher compression ratio and lower speed than WinRAR v4.x with 4 MB).
The software is distributed as a shareware and anyone may use it during a test period of 40 days at no charge.
While archiving with the RAR format is proprietary, Rarlabs supply as copyrighted freeware the source code of the UnRAR unpacker, with a license allowing it to be used in any software, thus enabling others to produce software capable of unpacking, but not creating, RAR archives.
- Pack (create) or validate (test) RAR and ZIP archives.
- Unpack ACE, ARJ, BZ2, CAB, EXE, GZ, ISO, JAR, LZH, RAR, TAR, UUE, XZ, Z, ZIP, ZIPX, and 7z archives.
- Multithreaded compression
- The ability to create self-extracting and multi-volume (split) archives.
- Data redundancy is provided in the form of recovery records and recovery volumes, allowing reconstruction of damaged archives.
- Support for advanced NTFS file system options
- Unicode in file names.
- Archive encryption using AES (Advanced Encryption Standard) with a 256-bit key.
There was a portable version of WinRAR called WinRAR Unplugged, which did not require installation or create dependencies on the host computer.
As of July 2014, WinRAR is available in 44 languages:
Arabic, Armenian, Belarusian, Bulgarian, Catalan, Chinese Simplified, Chinese Traditional, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, Galician, Georgian, German, Greek, Hebrew, Hungarian, Indonesian, Italian, Japanese, Korean, Lithuanian, Norwegian, Persian, Polish, Portuguese, Portuguese Brazilian, Romanian, Russian, Serbian Cyrillic, Sinhala, Slovak, Slovenian, Spanish, Swedish, Thai, Turkish, Turkmen, Ukrainian and Vietnamese.
- Command line RAR and UNRAR were first released in autumn 1993.
- Early development version WinRAR 1.54b was released in 1995 as 16-bit Windows 3.x application.
- Version 2.00 was released on September 6, 1996.
- Since version 3.00 (May 2002), the new RAR3 archive format is implemented. The new compressed archives cannot be managed by old versions of WinRAR.
- Since version 3.50 (August 2005), WinRAR adds support for interface skins and themes and support Windows XP x64.
- Since version 3.60 (August 2006), 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 (circa January 2007), WinRAR features support for Windows Vista.
- Since version 3.80 (September 2008), support for ZIP archives, which contain Unicode file names in UTF-8.
- Since version 3.90 (May 2009), WinRAR adds support Windows x64 natively and support Windows 7. Also it enhanced support for multithreading.
- Version 3.91 is the last version that supports Valencian.
- Version 3.92 is the last version that supports Serbian Cyrillic and Serbian Latin.
- Version 4.00 (March 2011) 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.
- Since version 4.10 (January 2012) 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.
- Since version 4.20 (June 2012) 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.
- Since version 5.00 (September 2013) the new RAR5 archive format is implemented. The new compressed archives cannot be managed by old versions of WinRAR. This new format features a maximum 1 GB dictionary (only in 64-bit version), better multicore support, it removes multimedia, text and Itanium binaries special compression algorithms.
Operating systems support
As with most software, the latest archive tools no longer support older operating systems. The following historical information is useful for supporting older versions of Windows (including Wine on Linux) and MS-DOS (including FreeDOS).
- WinRAR v5.x (current version) supports Windows XP and later.
- WinRAR v4.11 is the last version that supports Windows 2000.
- WinRAR v3.93 is the last version that supports Windows 95, 98, ME, NT.
- RAR v3.93 is the last version that supports MS-DOS and OS/2 on 32-bit CPU, such as 80386 and later. It supports long file names in a Windows DOS box (except Windows NT), and uses the RSX DPMI extender.
- RAR v2.50 is the last version that supports MS-DOS and OS/2 on 16-bit CPU, such as 8086 and 80286.
- In "About WinRAR" Help menu clicking on the WinRAR logo makes the ocean surf and waves move. Mouse clicking with Shift pressed on the logo causes the appearance of a sailboat above the "R" button which is sailing around in the water.
- In the same dialog pressing the book icon causes it to jump like a ball until it rests, and with each bounce, the Windows' exclamation sound can be heard.
- Colored comments can be added to WinRAR archives.
