WinRAR is an archiving utility that completely supports RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives. It consistently makes smaller archives than the competition, saving disk space and transmission costs.
WinRAR offers a graphic interactive interface utilizing mouse and menus as well as the command line interface. WinRAR is easier to use than many other archivers with the inclusion of a special "Wizard" mode which allows instant access to the basic archiving functions through a simple question and answer procedure.
WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits. It supports files and archives up to 8,589 billion gigabytes in size. It also offers the ability to create selfextracting and multivolume archives. With recovery record and recovery volumes, you can reconstruct even physically damaged archives.
Previous versions ignored files with invalid UTF-8 names inside of ZIP archives. Now WinRAR extracts such files, even though their names may include arbitrary text after unpacking.
5.50 beta 1 could crash when extracting some of broken RAR4 archives.
"Settings/Viewer/Unpack everything for" was ignored for files matching "Settings/Archives/File types to open as archives first" masks. Now it is changed, so "Unpack everything for" has a higher precedence for archived files. Files inside of archive matching "Unpack everything for" masks are processed according to that option even if they are also matched by "File types to open as archives first" masks.
