Final Version of WinRAR 4.0 Released

(March 10, 2011)

Berlin, Germany, March 10, 2011 --( win.rar GmbH and RARLAB present the final version of WinRAR 4.0. The world’s leading compression software now decompresses RAR Archives 30% faster than before. Even self-extracting archives are decompressed faster while using less resources. With the newly integrated password manager, users are able to have their favourite archive encoding passwords saved for future use. Moreover, the software's Unicode support has also been optimized.

30% faster decompression:

Thanks to RAR's improved and highly accelerated decompression algorithm, users can now extract their files up to 30% faster than with previous WinRAR versions. RAR users who normally work with large video or digital picture files will have something to look forward to since the increase in extraction speed is most noticeable with multimedia file extraction.

Save frequently used passwords with the new password manager:
Password protection of archives is one of the most important and most popular security functions of WinRAR. A frequently requested feature - a password manager - has been added to the new WinRAR 4. For the first time ever users can define and save their frequently used passwords with the new password organizer function. This way, the passwords can now be applied and retrieved easily and comfortably for file extracting purposes at any time. In addition, users can now extract several different files at the same time as long as they are encrypted with the same password. If no password is entered, WinRAR will automatically skip all encoded archives during the compression process.

Improved Unicode Support:
Another highlight of the new WinRAR version is the numerous improvements in Unicode support. For example, WinRAR 4.0 now supports non-English file names. Noticeable improvement can also be seen in WinRAR functions like "Rename", "Convert", "Find" and other commands, in the folder tree panel, in the password request dialog and in many other parts of the WinRAR interface. Thereby the data-transfer with business partners in other continents, that use the Cyrillic or Chinese alphabet has been facilitated. Moreover, reports can now be delivered in HTML or Unicode text files.

Further important innovations in WinRAR 4.0:
- WinRAR offers better Blu-ray Support: UDF support has been upgraded to UDF 2.50 revision, now making it possible to unpack most Blue-ray ISO files.
- WinRAR now offers the users the option to display passwords, if needed. Via the analogous password dialogue in the packing and unpacking process, passwords now can be visible during both processes.
- The SFX archive now has an optimized operation status and error messages display. Compared to the previous version, this change reduces the memory usage and improves the extraction process speed
