winrar 5 v 5.20 beta (32 and 64 bit) full version

        There are millions of RAR files in the world and most of them have been compressed with the algorithm RAR4, which can open almost all decompressors and almost all versions of WinRAR. WinRAR Version 5 introduces a higher standard, RAR5.

         For starters, RAR5 increases the compression dictionary size to 1GB (in the 64-bit version). The larger the dictionary, which stores the repeatable parts of a file, the better the compression, but only for huge files.

           The default size of the RAR compression dictionary is 32MB, a much lower figure. So when would you need to use large dictionary sizes? When you have huge files that you aren’t going to share, such as when you make a back up.

           Another important change is the new recovery log. RAR5 format is much more resistant to damage than RAR4, but only with a log size equal or greater than 5% of the file, even if it’s corrupted.

             Finally, with RAR5 you can encrypt your data with a 256-bit AES algorithm. It’s certainly not the strongest encryption on the market, but it is very, very robust. The U.S. government uses it to protect its Top Secret content.
