WinRAR Full Version

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.


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

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.

In the command line mode the text compression can be enabled with -mct switch  "Fastest" (-m1) compression mode also supports several processor  cores now. In 4.11 it could use only a single processor core.

Changes in ZIP compression:
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;

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.           

Now the allowed  value for -mt switch is 1 - 32, not 0 - 16 as before.

Windows 2000 is not supported by WinRAR and WinRAR self-extracting modules anymore.

Save current settings" button in "Advanced SFX options" dialog is now available only when converting an existing archive to SFX. Options saved with this button are applied only to convert to SFX operation. If you create or update SFX archive, only SFX options stored in default compression profile are used. Options saved in "Advanced SFX options" dialog are ignored for these operations.
