How to open P21 file?

The most common problem when using PAR Recovery Volume is that a specific P21 is not associated with the program. This causes the file P21 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the P21 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install QuickPar

An often overlooked issue is to make sure that QuickPar is installed on the computer. This can be achieved by typing QuickPar into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file P21.

Programs to open P21 file

Remember to download programs supporting P21 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of QuickPar with P21 files

If, despite the installed application, the P21 file does not start in the QuickPar application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the P21 file with the QuickPar application.

Step 3. Update QuickPar to the latest version

If, however, after binding QuickPar with PAR Recovery Volume there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Peter B. Clements website and install the latest version.

Step 4. Check for the following problems with the P21 file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to P21 files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file P21 or the program directory. However, remember that not every infected P21 file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the P21 file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular P21 file corruption. The easiest way to restore the file is from a backup or by contacting N/A, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted P21 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the P21 file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file P21 to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
