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. WinRAR is also ideal, if you are sending data through the web. Its 128 bit password encryption and its authenticated signature technology will give you the peace of mind you have been looking for.
Version 4.20 Changes in RAR compression: 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.
