Fedora 32, x64
After using your computer for a while, you will notice
that your "Open With" dialogue starts to fill up
with duplicates and others stray entries you don't
want. I have attached a screen shot (from Krusader)
showing the issue:
Thunar does not have the ability (or at least one I could
find) to handle this. But Krusader does:
--> right click on the file
--> select Properties
--> "File Options" (tab)
--> File Type Options (button half way down)
File Type Options gives you the ability to Add, Edit,
Remove entries from your Open With list. And it does
migrate to Thunar.
I have attached another screen shot of File Type Options
What a mess! I have to clean up .png something big time!
I have opened a Request for Enhancement (RFE) to
Thunar over at
RFE: give ability to delete Open With entries
Took me years to figure this out. Ed over on the
Fedora mailing list told me how.
