Can an enduser set the relation between app and file extention?

[AC Question]

I tried several apps that can read various file types including .msg files, the problem is that they can open .msg files from the file system but not through my backup application.

I am not sure i should reference the applications so I am using the terms msgapp and bacukapp but the behavior is the following:

In settings/apps/msgapp/Open by default there is no default set.

Case 1: I navigate with "Android File Manager" to "download" folder and tap on a .msg file. As expected the msgapp is used to display the file content (consider there is only one app capable to read .msg files).

Case 2: I attempt to view an .docx file from inside my backupapp for android and tap on the file from inside BackupApp. I am prompted with a list of apps, including msgapp, that can open .docx files. All of them work properly.

Case 3: I attempt to view an .msg file from my backupapp for android and tap on the file from inside BackupApp, I get the message "No apps found for viewing this type of file".

I believe it is a matter of definition from the msgapp side of the "intent filter" regarding .msg files but as an end user can I set myself the relation between any app and any file extention?

Welcome to the forums. I don't think this can be done. I think this is a limitation in the coding to build the app.
