WinRAR is a 32-bit / 64-bit Windows version of RAR Archiver, the powerful archiver and archive manager. WinRAR's main features are very strong general and multimedia compression, solid compression, archive protection from damage, processing of ZIP and other non-RAR archives, scanning archives for viruses, programmable self-extracting archives(SFX), authenticity verification, NTFS and Unicode support, strong AES encryption, support of multivolume archives, command line and graphical interface, drag-and-drop facility, wizard interface, theme support, folder tree panel, multithread support and Windows x64 shell integration. WinRAR provides complete support for RAR and ZIP archives and is able to unpack and convert CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, Z, 7-Zip archives. WinRAR is available in over 40 languages.

Changes in version 3.90 include: RAR compression speed is improved for multi-core and multi-CPU systems. This improvement is most noticeable in Windows Vista and Windows 7 operating systems. "Remove duplicate folders from extraction path" option in "Settings/Compression" dialog is replaced by more universal "Remove redundant folders from extraction path" option. If you sort files by name in the file list in WinRAR shell, WinRAR will use the new logical file name sorting, same as in Windows Explorer, considering digits in file names by their numerical value. Better shell extension performance--now WinRAR context menu will be more responsive when working with thousands of selected files.
