The most common cause of problems with opening the 7Z file is simply the lack of appropriate applications installed on your computer. In this case, it is sufficient to find, download and install an application that supports the 7Z file format - this type of programs are available below.

Enter the file extension
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 7Z files.
Often, an installed application should automatically link to a 7Z file. If it did not happen, the 7Z file can be linked with the newly installed application manually. Simply right-click on the 7Z 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.
However, problems with the 7Z files can also have a different background. Sometimes even the software, installed on your computer, that supports the 7Z files does not solve the problem. The reason for the fact that the 7Z file can’t be opened and used can also be:
- an incorrect link to the 7Z file in the registry entries
- corruption of a 7Z file, that you want to open
- infection of a 7Z file (viruses)
- insufficient computer hardware resources
- drivers out of date
- accidental deletion of the 7Z file from the Windows registry
- incomplete installation of the program that supports a 7Z file?
Solving these problems should allow the free opening and working with the 7Z files. If the computer still has problems with the files, use the services of an expert who will diagnose a specific cause.
In the standard Windows settings, a computer user cannot see the 7Z 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 7Z files should be displayed after the file name.
