RAR is archive file format of WinRAR that supports file spanning, error recovery and data compression. RAR is an advanced compression technique that is created by a Russian programmer named Eugene Roshal. RAR is an acronym for Roshal ARchive. In order to save the storage space and bandwidth data compression technique is used. Hence, data compression relies on RAR and other archive file formats. Archive files accumulate various related files within an enclosure. File spanning is a technique of RAR that splits a single archive into many smaller files. This is very helpful for storing large files on smaller volumes or for transferring huge amount of data over a network. By using this technique of compression large files such as videos or programs, can be downloaded into smaller chunks. This attribute is useful for transferring data over channels with limited bandwidth. RAR tool is mostly used for data compression, whenever you try to download or upload files from remote servers. RAR files are protected with the help of password for securing data. If the password protected RAR files are corrupted due to some reasons then you suffer from data loss. To overcome data loss you need to fix RAR file which are broken by using efficient RAR repair utility.

RAR files are corrupted due to several reasons. If there is insufficient memory to carry out the compression operation then the RAR files get corrupted. If some third party application alters the file extension then also the RAR file gets corrupt and leaves it inaccessible.  If RAR files are infected by some harmful malware or virus or during the anti-virus scan process if it detects any threat in RAR files then it deletes it and result in loss of files. If the RAR file structure is damaged then the cyclic redundancy check, or CRC error stops you from extracting its contents and you get an error message like "Cannot open file: it does not appear to be a valid archive" and result in file loss. If you have downloaded a file improperly from internet then an error occurs while opening it that interrupts unzipping process and results in loss of file.
