Level of difficulty: Intermediate Consistent with other archive formats, the RAR file may contain one of more files within a single file. It may also represent an archive which is part of a bigger volume that is intended to minimize the storage space occupied by computer files based on a specific mathematical algorithm. Developed and introduced by the Russian Eugene Roshal, the RAR (Roshal Archive) makes use of a compression method that is about eight to 30 percent smaller in size compared with the more popular ZIP format archive but may take a longer compression time to produce the smaller file size. This archive format also incorporates redundancy methods that allows for the repairing of damaged archive files. This includes the support for non-English character sets which produces non-conventional filenames. There are currently no Operating System platforms that have built-in support algorithms for this archive format which is why users need to acquire the WinRar software or its corresponding freeware utility.
