WinRAR is a shareware file archiver and data compression utility developed by Eugene Roshal and distributed by Ron Dwight, first released in autumn of 1993.[3] It is one of the few applications that is able to create RAR archives natively, because the encoding method is held to be proprietary. Command-line versions, simply called "RAR", exist for Mac OS X, Linux, and FreeBSD.

Features[edit]
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, Z, and xz archives.[5][6]
- Multithreaded compression
- 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.
WinRAR Unplugged, a portable version of WinRAR, was available in the past and it didn't require installation, neither it created dependencies on the host computer.
Version history[edit]
Below is a summary of notable WinRAR milestones. Version 2.00 was released on September 6, 1996.
- Since version 3.00, 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.[7]
- 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.[8]
- Since version 3.80, support for ZIP archives, which contain Unicode file names in UTF-8.[9]
- Since version 3.90, WinRAR adds support Windows x64 natively and support Windows 7. Also it enhanced support for multithreading.[10]
- 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.[11]
- 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.[12]
- 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.[13]
- Since version 5.00 Beta 1 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 1GB dictionary (only in 64bit version), better multicore support, it removes multimedia, text and itanium binaries special compression algorithms.[14]
Easter Eggs[edit]
- 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 you 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.
- You can add colored comments to WinRAR archives.[15]
