WinRAR is a powerful archive manager. It can backup your data and reduce the size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format.
WinRAR is a powerful compression tool with many integrated additional functions to help you organize your compressed archives.
WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well.
WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).
WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries particularly well.
WinRAR allows you to split archives into separate volumes easily, making it possible to save them on several disks for example.
Admittedly, WinRAR is slightly slower in compressing files when compared with the similar products but its compressibility is almost the best among them, which means that the files produced by WinRAR is obviously much smaller. Besides, it is able to restore documents if some errors were occurred even when they are heavily and physically damaged.
Apart from the standard function, WinRAR provides some additional options. It allows each document be secured by a password without which the document cannot be opened. If the user set a properly complex password, the application will secure the file with the use of AES (Advanced Encryption Standard), which promises that the password cannot be cracked by most of decrypting applications. Although in the process of compression WinRAR draws on considerable amounts of the system resources, its flexibility is able to adjust itself to individual’s computer capabilities and environment so as to make it smoothly run on some less advanced computers.
1. RAR 5.0 archives can include an optional quick open information
controlled with -qo[-|+] switch or "Quick open information" options
group in archiving dialog. It allows to open the archive contents
in WinRAR faster.
This version provides better update performance for archives
containing both quick open information and service records,
such as NTFS file security. Also default parameters of quick open
information are optimized to achieve faster open time for such
2. Bugs fixed:
a) "Find" command could fail when searching text string in .7z
b) when opening RAR 5.0 archive with encrypted file names stored
in another such archive, WinRAR could issue an erroneous message
that password is incorrect. It happened only if passwords to inner
and outer archives were different. It did not affect extraction,
all files could be unpacked regardless of this message;
c) option "Use for all archives" in password dialog did not suppress
additional password requests for RAR 5.0 archives with encrypted
d) WinRAR address bar did not process correctly environment variable
based paths, such as ;
e) storing NTFS file security and alternate data streams did not work
for file pathnames longer than 260 characters;
f) "Test" command could erroneously report damaged data in valid
recovery record if only a part of files in RAR 5.0 archive
was tested. It did not happen if entire archive contents was
g) "Test" command erroneously reported errors when verifying
RAR 4.x Unix symbolic links;
h) WinRAR "View" command did not work for files inside of BZIP2
