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.
"Name encoding" submenu in "Options" menu allows to select encoding for archived file names. This selection affects archive browsing and extraction commands. You can use the Ctrl+E keyboard shortcut to access this menu quickly. It can be useful when unpacking an archive without Unicode file names, for example, unpacking a zip file with Chinese archived names in Windows, with Russian specified as a language for non-Unicode programs.
Usability enhancements, like dragging folders from folder tree panel and dropping them to other programs or Desktop to copy or unpack them have been added. You can drag the archive icon in tree panel root to unpack the entire archive.
Furthermore, the maximum comment length for RAR archives has been increased from 64 to 256 KB. Since SFX script commands are stored in archive comment, it allows now a longer main and license text in an SFX archive.
As you might know you can secure your archives with Recovery Records. If an archive has a Recovery Record, it can be repaired even after having been damaged due to a defect on a disc or other data loss. The ZIP format does not support Recovery Records. Now with the new version WinRAR 5.40 Recovery Records (.rev files) are present in the same folder as usual RAR volumes and archive test command verifies .rev contents after completing the test of .rar files.
Previously "Synchronize archive contents" update mode (-as command line switch) aborted if some of archiving folders could not be read. Now WinRAR continues performing the operation and preserves archived files matching unreadable folders.
