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.

WinRAR entry in Windows Start menu uses Desktop as a start folder, so Desktop contents is shown after opening WinRAR. Previously it had the start folder blank, which resulted in displaying Windows system files on start.
If wrong password was specified for ZIP archive, the previous beta issued an error message with "OK" button for every encrypted file even if password was specified with "Set default password" command or -p<pwd> switch. Now users do not need to press "OK" repeatedly for globally set wrong ZIP passwords.
