PAR extension file has been corrupted!
You are unable to open .par extension!
The PAR file has been created by Dedicated Micros DVRs which contain video files. The PAR extension file is mainly known for Parity Volume Sets. Because of these unique Parity Volume Sets you can recreate missing volumes from a set of files. The unnecessary data in the PAR files is computed using Reed-Solomon codes. A set of equal-sized blocks of data and a number of similar recovery blocks are produced by Reed-Solomon codes. If the number of files missing is more than the number of parity volumes then it will not function.
There is an index file which contains a group of parity volumes recover a file archive when one of the files in the archive is lost. The .PAR extension file can easily go with a file archive set like WinZip. Files such as video, audio, and other multimedia data can remain in a working format and still have recovery data associated with them. The PAR file itself is made of packets with their own checksum. This feature prevents it from unusable. If one file has been corrupted after that it will perform.
Incorrect links are the cause of errors in PAR extension files. Virus or any malfunctioned programs can also damage your PAR files. Routinely scanning of your system can prevent and repair PAR file errors. If any of the data files were damaged or lost while being circulated between servers, users could download parity files and use them to repair the damaged or missing files. Parchive contained the structure of small index files that do not contain any recovery data. These indexes contain file hashes that can be used to find out the target files and validate their reliability.
