I'm using Ubuntu 21.10 with Nemo as my default file manager (because I like the split screen)
I was trying to change a default application to set Edrawmax to open .eddx files.
If I go to Nemo or Nautilus | Properties of the file | Open with and browse through the list of applications I see this:
Note the two entries for edrawmax. They were not there the first time I tried this, I had to type 'edrawmax' in the commandline box. It worked fine then but for some reason reverted back to archive manager being the default application (probably after a recent regular application upgrade). I went to rest Edrawmax as the default app for eddx files and selected one of these. When I double clicked on the file Edrawmax spat an error saying it could not open the file.
I tried the same thing using Thunar. It shows this:
Note the extra entry for Edrawmax with the applications actual icon beside it. But even selecting this I got the same error, that Edrawmax could not open the file.
I then (in Thunar) typed edrawmax in the commandline input and that worked, I can now double click on a .eddx file and it opens correctly in Edrawmax.
My questions are:
Where are these entries stored so I can remove those two entries for edrawmax in nemo?
and
Why did the program (with icon) not show in Nemo or Nautilus but did in Thunar?
and
When I set it to work I had to type the command in the box to get it to work rather than select the item in the list (even the one with the icon in Thunar)?
