Winrar 5.40 Beta Version Free Download

WinRaR Full Version Free Download

WinRAR 5 (32 Bit and 64 Bit) is a powerful archive manager. It can backup your data and reduce the size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and Zip files format. Changes in RAR  compression RAR general compression algorithm is optimized for better utilization of several processor cores. While some speed gain is possible even in single processor mode, best results are achieved in multi-core environment. Speed gain depends on data type and average file size. Several cores are utilized more efficiently when compressing large files.

What is New in WinRAR 5.40 Beta 1 Version

1. “Drag and drop context menu” options in “Settings/Integration/ Context menu items” dialog allow to disable WinRAR archiving and extraction commands in context menu displayed after dragging and dropping files with right mouse button.

2. If winrar.ini file is present in the same folder as WinRAR installer, winrar.ini will be copied to WinRAR program folder after completing installation.

3. While previous versions could produce RAR5 volumes of slightly smaller than requested size sometimes, such situation is less likely now. In most cases volume size equals to specified by user.

4. Bugs fixed:

a) WinRAR 5.31 issued unnecessary user account control (UAC) prompt, when running an executable from archive stored in UAC protected folder. Since nothing is extracted to folder containing an archive in such case, UAC prompt is not needed;

b) WinRAR could overwrite files with read-only attribute only when unpacking RAR and ZIP archive formats. Now it is also implemented for other archive formats supported by WinRAR;

c) “Elapsed time” and “Time left” were displayed incorrectly when applying “Convert” command to multiple archives and enabling “Add recovery record” option.

WINRAR 32 Bit had to increase memory requirements to achieve higher compression speed. General RARcompression algorithm allocates about 120 MB comparing to 40 MB in WINRAR 4.
WINRAR 64 Bit text compression algorithm cannot utilize several CPU cores efficiently, so its performance in multiprocessor environment is much lower than for general algorithm. Also its decompression speed is much lower than in general algorithm regardless of CPU number. So we decided to disable the text algorithm by default. If you need maximum possible compression ratio for plain text data regardless of speed, you can enable the text compression in “Advanced compression parameter” dialog. Press “Compression” button on “Advanced” page of archiving dialog to access it. You can also change this option permanently in default compression profile; In the command line mode the text compression can be enabled with much switch.

“Fastest” (-m1) compression mode also supports several processor cores now. In 4.11 it could use only a single processor core. WINRAR x64 general decompression algorithm speed is slightly improved,though not same extent as RAR compression. RAR decompression is not able to use several processor cores, so its performance does not depend on a number of cores. Changes in ZIP compression: now ZIP compressionsupports several processor cores resulting in noticeably higher performance in multi-core environment. Single CPU ZIP compression is also faster than in 4.11; Memory use for ZIP compression is increased to about 15 MB.
