It seems "Delete prefix" menu in Prefix tab page does not actually remove the prefix folder in ~/.local/share/wineprefixes/
Steps to reproduce:
Hi @fourzerofour .
This is desired behaviour: q4wine deletes only database record, since I won't force user to remove his files.
However, I think it is possible to add an checkbox option for folder removal (it will be unchecked by default)
This commit: 5dd5ec4 will add requested feature. See image below.
Since I won't q4wine to force user to delete his local files, by default, this option is unchecked.
Test the solution while you have free time.
Feel free to reopen this ticket if needed.
