| PAR2 Recovery Volume Format | Parchive | Compressed Files |
The PAR2 file extension is used for the Parchive 2 Index files. It is a storage container that is used to store error-correction information for files that have been split into pieces. This helps to ensure that any damage or corruption to the original parts can be rebuilt and the original, undamaged file can be recovered. This file type is used in the QuickPar software application which enables the repair and reconstruction of files from Usenet postings.
Technical Details
The PAR2 files are typically a few kilobytes in size and contain standard XML-based data. This data contains a checksum and other information that is used by QuickPar, or other similar apps, to determine how much damage has occurred to the parts of an archive and then to create a new, correct version of the damaged parts. The PAR2 file is usually packaged alongside the part files (the original.rar or.zip files) as a single file set to help facilitate secure data transmission.
PAR2 files are related to many other indexing and repair files such as: .crc, .md5, .psf, and .diz. All of these extensions are used to detect file corruption and often enable automated tools create reconstructed versions of a broken download.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PAR2) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .PAR2 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .PAR2 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .PAR2 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .PAR2 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PAR2 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .PAR2 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .PAR2 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PAR2 file) will be extended to the maximum.
It is also good to check
- if the .PAR2 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
