To check a particular archive, download the smallest PAR2 of the set. Programs like QuickPar can be used to open parity files and use them to check the integrity of the RAR file archives. PAR2 files вЂ“ Howard Fukada specified that the new format work on the blocks of data that make up the RAR file instead of repairing the whole file. If the damage is small to a large RAR file, it requires a repair file that is of equal size to fix it.Д«ecause of the limitations, PAR format was replaced by PAR2 format a year later.

They cannot be used to repair part of a RAR file (repair the individual blocks that make up corrupted RAR file).

It can only handle or repair up to 255 files.

Although PAR was a popular format and required less system resources, it suffered some limitations. They were the initial standard for repairing or reconstructing broken RAR files on Usenet. Par1 files used the Reed-Solomon error correction method to create recovery files. Before PARs were developed, the only way to replace a bad RAR file was to ask the user to repost the file. These files were used to verify the integrity of the RAR files that were uploaded to Usenet or allow for the recovery and reconstruction when a RAR file is incomplete or corrupted. In 2001, a team (Rieper and Wehlus) proposed the PARCHIVE or PARвЂ“ (Parity Volume Set specification) to solve the problem of reliably posting large files onto Usenet.

Many times people refer to Parity Files as PAR and PAR2.

PAR is short for PARCHIVE which is also short for Parity Archive Volume Set. To check if your RAR files are corrupt you want to always download the smallest PAR2 file in the group. When downloading a particular RAR archive you do not need to download the PAR2 files unless the file is obviously damaged. Certain RAR files are incomplete because something may have happened during the upload process to Usenet which affected their completion (like a connection interrupted during upload, issues with propagating to Usenet correctly, etc.). Some of those RAR files may be corrupt and the parity files are there to either fix the entire archive or just rebuild part of the archive. Sometimes when an archive is uploaded to Usenet, it is uploaded as several RAR files and a few PAR2 files that follow it.

Parity files are used to check the integrity of the RARвЂ™s and repair broken archives. Ever wonder what those files were? Well NewsgroupReviews will try to explain it in a simple, easy to understand tutorial. If you don't it's quite likely to be pirated content.Have you ever browsed your favorite newsgroups and seen articles that have PAR or PAR2 files attached? These files usually accompany the RAR files in the entire archive.

To test this out, I would attempt to re-download it on a different Windows computer with RAR on it and see if you get a better result. We usually don't pry into what your source file contains, but you should know that if you got your file from one of these P2P or other sites, it's quite likely to be rendered inoperable permanently and commercial recovery software, even fee-based, may not be capable of repairing. This is especially true if you got this file from any kind of P2P file sharing site such as the old Napster site, uTorrent, or Pirate Bay.

It might also be worth mentioning, since we don't know what kind of file your TAR file is composed of, if it's an audio or video file and contains copyrighted music or movies covered under the DRM Act of 2006, there is software floating around on the Internet that searches out and corrupts or destroys the contents of these files since it's a direct copyright infringement to redistribute these files without royalties being paid.
