WinRAR 4.20 Beta 1

WinRAR 4.20 Beta 1  | 2.8MB

WinRAR - one of the most popular archivers. The fact that it supports the backup format RAR, it will probably not need to explain. In addition, the program can work with archives ZIP, CAB, ARJ, LZH, TAR, GZ, ACE 2.0, BZIP, JAR, UUE, GZIP, BZIP2 and 7-Zip, while it has many very useful features - encryption, support of continuous (solid) archives in which the compression ratio can be 10 - 50% more than the usual methods of special compression algorithm compresses multimedia files, support of multivolume archives, and many others.
.

Features:
* Full support for RAR and ZIP archives
* The use of the original high-performance data compression algorithm
* The presence of a graphical environment that supports drag and drop (drag & drop)
* Ability to use the command line interface
* Manage archives of other formats (CAB, ARJ, LZH, TAR, GZ, TAR.GZ, BZ2, TAR.BZ2, ACE, UUE, JAR, ISO, 7Z, Z)
* Support for the method of continuous backup for better compression
* Support of multivolume archives
* Create self-extracting (SFX) and multivolume archives normal with a standard or optional SFX modules
* Ability to recover physically damaged archives
* Ability to create and use of recovery volumes, allowing to reconstruct missing parts of multivolume archives.
* Support for Unicode encoding in filenames
* Additional features (data encryption and file names in the game, adding archive comments, error logging)
* The use of third-party registration interface in the form of individual topics

What's new in this version:
A. Changes in RAR compression:
a) 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.
b) we had to increase memory requirements to achieve higher compression speed. General RAR compression algorithm allocates about 120 MB comparing to 40 MB in WinRAR 4.11;
c) RAR 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-mct switch;
d) "Fastest" (-m1) compression mode also supports several processor cores now. In 4.11 it could use only a single processor core.
Two. RAR general decompression algorithm speed is slightly improved, though not to 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.
Three. Changes in ZIP compression:
a) now ZIP compression supports several processor cores resulting in noticeably higher performance in multi-core environment. Single CPU ZIP compression is also faster than in 4.11;
b) memory use for ZIP compression is increased to about 15 MB.
4. Recovery volume creating and processing can use several CPU cores resulting in higher speed. Though, typically hard drive seek speed is a limiting factor for recovery volumes, so this gain is most noticeable when working with solid state drive.
Five. Now the allowed value for-mt switch is 1 - 32, not 0 - 16 as before.
6. "Find files" command can search data in 7-Zip archives. Previously "Find files" did not support .7 z archive format.
7. Windows 2000 is not supported by WinRAR and WinRAR self-extracting modules anymore.
