The archive is usually a regular file, which name has a ".rar" suffix.

Features:

  • RAR introduces an original compression algorithm. It allows higher compression ratios than other PC archiving tools, especially on executable files, object libraries, large text files, etc.
  • RAR offers an optional compression algorithm highly optimized for multimedia data.
  • RAR provides functionality for creating a 'solid' archive, which can raise the compression ratio by 10% - 50% over more common methods, particularly when packing large numbers of small files.
  • RAR offers the ability to create and change SFX archives using default and external SFX modules.
  • RAR offers the ability to create a multi-volume archive as SFX.
  • RAR offers a number of service functions, such as setting a password, adding archive and file comments. Even physically damaged archives may be repaired and an archive may be locked to prevent further changes. Authenticity information may be added for additional security and RAR will store information on the last update and name of the archive.

What's New:

  • Ctrl+A keyboard shortcut selects the entire text in WinRAR comment window.
  • If -idn switch is used together with -t or -df in console RAR when archiving, it additionally disables "Deleting <filename>" or "Testing <filename>" messages, normally issued by these switches. Also -idn disables folder creation messages when extracting a file to non-existing folder.
  • WinRAR and ZIP SFX module refuse to extract contents of ZIP SFX archives if ZIP central directory is resided after beginning of Authenticode digital signature. It is done to prevent possible attacks with inclusion of ZIP archive into signature body.

Bugs fixed:

  • "Convert archives" command could incorrectly convert Unicode comments in RAR archives.
  • If two archive information windows had been opened from Explorer context menu, the compression ratio bar in the first window could erroneously display a value for second archive. It did not affect the ratio and other text details at the right of window. Only the vertical bar at the left could be updated to a wrong value;
  • If "Wait if other WinRAR copies are active" option was enabled in extraction dialog, "Waiting for another WinRAR copy" title was not set in command progress window while waiting; d) when extracting a symbolic link, previous versions did not overwrite existing symbolic links even if user requested it in overwrite prompt.
