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.
New Features:
RAR general compression algorithm is optimized for better
utilization of several processor cores. While some speed gain
is possible even in single processor mode, best results
are achieved in multi-core environment.
Speed gain depends on data type and average file size.
Several cores are utilized more efficiently when compressing
large files.
we had to increase memory requirements to achieve higher
compression speed. General RAR compression algorithm allocates
about 120 MB comparing to 40 MB in WinRAR 4.11;
RAR text compression algorithm cannot utilize several CPU cores
efficiently, so its performance in multiprocessor environment
is much lower than for general algorithm. Also its decompression
speed is much lower than in general algorithm regardless of
CPU number. So we decided to disable the text algorithm by default.
