How do you remove the default open with application for a file extension? Not change it but remove it so when I try to open it a popup says
"There is no application set to open the document “file.blabla”.
Use RCDefaultApp. With it, you can set the file association to
All you need to do is right click on the file that you want to open, click "get info" (in the dropdown list) then click "Open with"
After that, select the application you want to open it up with, and select "Change all"
Hope this helps!
