Compression and Uncompression Are Much Faster Now!          Download WinRAR 4.20 Beta 1

The first Beta of WinRAR 4.20 is ready for download. This version has significatly improved the speed compared to older versions of WinRAR.

May 03, 2012 - WinRAR.co.nz,  win.rar GmbH and RARLAB are proud to present the public the first Beta version of WinRAR 4.20. You  will now find that the compression speed for RAR is up to three times higher than in previous versions and this improvement is also valid for our ZIP compression.

Speed Improvements for RAR Compression
Quad core CPUs are becoming mainstream and affordable as users pay more attention to multicore efficiency. The Primary target of WinRAR 4.20 has been to utilise this efficiency.

By utilising the more avialable RAM and CPU improvements, the RAR compression speed in even single core mode CPU's has been raised considerably even though the main optimization has been made for multicore mode. For the typical average data mix, the speed of RAR compression is now twice as fast as WinRAR 4.11, while poorly compressing data such as .jpg and .mp3 is now three times faster. The speed difference between this new version and previous versions increases with a larger number of cores.

Speed improvements for ZIP Compression
Our ZIP Code has been rewritten and is now using similar techniques to the RAR compression, making WinRAR 4.2 ZIP compression faster than WinRAR 4.11, even in single core mode, by about 70%. By utilizing the multicore support in 4.20 ZIP, it can be up to 3 times faster than 4.11.

Additional improvements within the beta version of WinRAR 4.20
The RAR format continues to have many advantages like archiving, conversion, security and recovery functions. Recovery functions now also access multiple core processors in order to achieve time-savings when repairing files.
