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 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.
