Multithreaded rar

Added decompression of LZH archives created with "-lh7-" algorithm. New "Define volume sizes This button activates "Define volume sizes" dialog. Here you can customize the list of predefined volume sizes associated with "Split to volumes, bytes" field in archiving dialog.

Speed of RAR general compression increased for some data types. New "Rename automatically" option in the extraction dialog and command line -or switch to rename extracted files automatically if file with the same name already exists.

You can also enable the auto-renaming mode directly from the overwrite confirmation prompt with "Rename All" button. Renamed files will get names like 'filename N. Previously it could be changed only for RAR archives. New 'ch' change archive parameters command line mode command. Its purpose is to apply switches like -av, -tl and -cl to archive.

New 'cv' command line mode command. It is supported only by winrar. New command line -sl and -sm switches to set size limits of processing files. New command line -fcu[file] switch allows to read archive comments from Unicode files. It also modifies behavior of "cw" command, setting the comment output format to Unicode. Previously it was supported by only archiving command. It is allowed to use environment variables in archive name in archiving dialog, in destination path in extraction dialog, in folder names on "Compression" and "Paths" pages in WinRAR settings.

The point of programming an application to use multiple threads, when speaking about a CPU intensive operation, is to split the work amongst the multiple CPUs. The screenshot above shows I have one logical processor. If I had two logical processors, you would clearly see two CPU graphs.

If enabled, WinRAR will use the multithreaded version of RAR compression algorithm providing the higher speed on multiprocessor architectures.

This option it is ignored when compressing to ZIP format. By default this option is turned on if number of processors reported by operating system is more than one, but it is possible to enable it manually even in the single processor system. You can use Benchmark and hardware test command to check if multithreading improves performance in your configuration.

The "Benchmark and hardware test" is found under the "Tools" menu. If you have WinRAR tips you would like to add, please contact us. We make intensified arcade-style retro games.
