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- drivers out of date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