RAR 5.90

Description

RAR is a compression program offering an original algorithm. This new way to compress files provides greater efficiency, and makes smaller archives — especially on multimedia files and archives with many files. RAR also offers self-extracting capabilities as well as disk-spanning (or multi-volumes). RAR is the official RAR archive utility for OS X (offered as a command-line utility), especially useful while reading all those alt.binaries newsgroups.

To use the RAR command-line application, place the files in any folder on your hard drive, and call the utility by typing in the full path to the application (e.g., to run from the current directory, type “./rar” or “./unrar” followed by the appropriate parameters). Typing the application name (rar or unrar) without any parameters will produce a helpful guide to each program’s usage.

What's New Version 5.90

  • RAR compression speed is improved for CPUs with 16 and more cores.
  • "Fastest" method (-m1 command line equivalent) typically achieves a higher compression ratio for highly compressible data types when creating RAR5 archives.
  • Maximum number of utilized threads is increased from 32 to 64. Command line -mt switch accepts values from 1 to 64.
  • "Repair" performance for RAR5 archives with recovery record and without data shifts is improved. It deteriorated in RAR 5.80 and is now restored to original level.
  • Password prompt is not issued when performing recovery record based repair for RAR5 archives with encrypted file names. This command can be performed without providing a password.
Bugs fixed:
  • "Repair" command could erroneously display "Recovery record is corrupt" message when processing an archive with valid recovery record. This message did not prevent further repair operation.
