What is PNP file?

The PNP file has been categorized as Settings Files. The creator of this file is David Harris. Settings Files consists of 1305 similar files. Pegasus Mail POP3 Server Side Filter Rule appears on 1 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is Pegasus Mail. This was created by David Harris.

How to open PNP file?

The most common problem when using Pegasus Mail POP3 Server Side Filter Rule is that a specific PNP is not associated with the program. This causes the file PNP to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the PNP 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 Pegasus Mail

The first step is to check if the computer has the Pegasus Mail program installed. This can be achieved by typing Pegasus Mail into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file PNP with Pegasus Mail. Later in this article you will find a list of programs that can open PNP files.

Programs to open PNP file

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

Step 2. Create association of Pegasus Mail with PNP files

If the application is or has been freshly installed, but the PNP file still does not use the Pegasus Mail program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. 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. Checking the "Always use the selected program ..." box will permanently associate the PNP file with the Pegasus Mail program.

Step 3. Update Pegasus Mail to the latest version

If, despite the association of the Pegasus Mail program with the Pegasus Mail POP3 Server Side Filter Rule file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the David Harris website or update the program from the application.

Step 4. Check for the following problems with the PNP 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. This is most often caused by a problem while downloading the PNP file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the PNP file that we want to open. However, remember that not every infected PNP file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the PNP files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged PNP files. The easiest way is to restore the file from a backup, if there is one, or contact David Harris
When reading, a message appears that the file was encrypted or corrupted. The encrypted file PNP except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. Copying the PNP file to another location will fix the problem.
This problem only occurs with more complex files. In this case, the PNP file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the PNP file for a certain period of time. If the problem persists, restart the machine.
