I tried this option on several directories.
Example, I have 2 directories:
- (2002) - A Album
- (2003) - B Album
- I drag and drop the directories to mp3tag window
- I select all songs
- I click "Export" button on toolbar
- I check "One file per directory"
- I select a configuration and click "OK"
When I look into "(2002) - A Album", there is no file named "mp3tag.txt" but when I look into "(2003) - B Album", there is a file named "mp3tag.txt"
I tried this several times on different directories. Result is the same.
I have version 2.55a.
