Even bludgeon obvious, ask at the outset that one of the major advantages of WinRAR is the management’s unwavering excellent Rar format. Compared to Zip, it appears indeed much higher compression ratio regardless of the settings: fast compression, standard and maximum. On the most common files including text files, the advantage is of the order of 2 to 5%.
But this bonus can reach 30 or even 50% for some media files (those that are not already compressed), for which WinRAR has a specific algorithm. For example, a complex uncompressed TIFF 21.8 MB will turn into a zip file of 18.9 MB, while archive.rar will occupy only 17.2 MB
In return, the compression time is also important. This is where the estimation module, which provides a forecast balance of size, length and compression ratio of a file / folder in the zip and rar three different compression levels. Although it is only an approximation, this module allows you to choose knowingly type and compression format before launching the operation on files / folders very large.
In addition rar and zip formats, managed comprehensively (compression / decompression), WinRAR decompresses as other archive formats: arj, lzh, can, ace, cab, gzip and UUE. The interface is very intuitive, allows a snap to open an archive, to inspect the contents, extract files or otherwise create / complete archive. Note that the compression / decompression operations can also be accessed via the Windows Explorer context menu.
To these basic functions are added in other handy such as testing and repair of archives, the distribution of an archive multivolume (very useful for breaking a large archive on several diskettes or more messages) creating a self-extracting archive (compatible with the previous option), password protection and certificate of authenticity or adding comments.
