RAR for Mac OS X 5.00 Beta 4

Allows you to manage and control archive files. The archive is usually a regular file, which name has a ".rar" suffix.

Features:

RAR introduces an original compression algorithm. It allows higher compression ratios than other PC archiving tools, especially on executable files, object libraries, large text files, etc.
RAR offers an optional compression algorithm highly optimized for multimedia data.
RAR 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.
RAR offers the ability to create and change SFX archives using default and external SFX modules.
RAR offers the ability to create a multi-volume archive as SFX.
RAR 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. Authenticity information may be added for additional security and RAR will store information on the last update and name of the archive.

What's New:

Fixed XZ archive support, which did not work in beta 2.
"Convert" command did not allow to use compression dictionaries exceeding 4 MB.
If both encryption password and archive comment were specified when creating RAR archive, archive comment was not added.
"View as Unicode (UTF-8)" command in internal viewer did not work, so UTF-8 files were displayed correctly only if their encoding was detected by viewer automatically.
Maximum compression dictionary size when running in Windows XP x86 is reduced to 128 MB. WinRAR cannot allocate enough memory to create archives with 256 MB dictionary in Windows XP x86.
Corrections in relative path processing, such as "..arcname.rar" name in archiving dialog or "WinRAR foldername" in the command line.
