Hint

It should be noted that some coded data from files that your computer does not read can be sometimes previewed in a Notepad. This way, we will read passages of a text or numbers. It is worth checking if this method can also be applied to the P7R files.

What should be done when an application from the list has already been installed?

Often, an installed application should automatically link to a P7R file. If it did not happen, the P7R file can be linked with the newly installed application manually. Simply right-click on the P7R file, then from the available list select "Choose default program". Next, select "Browse" and find the application you selected. These changes have to be confirmed by pressing the "OK" button.

Why can’t I open the P7R file?

However, problems with the P7R files can also have a different background. Sometimes even the software, installed on your computer, that supports the P7R files does not solve the problem. The reason for the fact that the P7R file can’t be opened and used can also be:

- an incorrect link to the P7R file in the registry entries
- corruption of a P7R file, that you want to open
- infection of a P7R file (viruses)
- insufficient computer hardware resources
- drivers out of date
- accidental deletion of the P7R file from the Windows registry
- incomplete installation of the program that supports a P7R file?

Solving these problems should allow the free opening and working with the P7R files. If the computer still has problems with the files, use the services of an expert who will diagnose a specific cause.

My computer does not show file extensions, what should I do?

In the standard Windows settings, a computer user cannot see the P7R file extension. However, you can successfully change this in the settings. Just go to "Control Panel" and select "Appearance and Personalization". Then, go to the "Folder Options" and open the "View" tab. On the "View" tab, you will find "Hide extensions for known file types" – you should mark this option and confirm by pressing "OK". At this point, the extension of all files, including the P7R files should be displayed after the file name.
