Here are some key features of "WinRAR":
· WinRAR introduces an original compression algorithm. It provides high compression ratios on executable files, object libraries, large text files, etc.
· WinRAR offers an optional compression algorithm highly optimized for multimedia data.
· WinRAR supports files and archives up to 9,223,372,036,854,775,807 bytes in size, about 9000PB. The number of archived files is unlimited for all practical purposes.
· WinRAR provides complete support for RAR and ZIP 2.0 archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, Z, 7Z archives.
· WinRAR supports NTFS file security and data streams.
· WinRAR offers both a classic interactive Windows interface and the command line interface.
· WinRAR provides functionality for creating a 'solid' archive, which can raise the compression ratio by 10% - 50% over more common methods, particularly when packing large numbers of small files.
· WinRAR offers the ability to create and change SFX archives using default and external SFX modules.
· WinRAR offers the ability to create a multi-volume archive as SFX.
· WinRAR offers a number of service functions, such as setting a password, adding archive and file comments. Even physically damaged archives may be repaired and an archive may be locked to prevent further changes.
· The number of files, which can be added to an archive, depends upon the amount of available memory and the length of file names. Roughly 128 bytes of memory are required per archived file for RAR archive. For example, it can take about 128 MB to compress one million of files. WinRAR has been tested to handle over one million of files.
· The size of a RAR archive, as well as the size of any single file within a RAR archive, is limited to 8,589,934,591 GB (9,223,372,036,854,775,807 bytes). Note that to create archives larger than 4 GB, you need to use NTFS, as older file systems do not support such large files.
· The size of a ZIP archive, as well as the size of any single file within a ZIP archive, is limited to 2 GB.
· In general RAR archive format is much better optimized for heavy tasks involving huge number of files and gigabytes of disk space.

What's New in This Release:
· 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.
· "Find files" command can search data in 7-Zip archives. Previously "Find files" did not support .7z archive format.
· Windows 2000 is not supported by WinRAR and WinRAR self-extracting modules anymore.
· 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.
· "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 ...
