Delete Duplicates doesn't show fullpath of moved file when configured to move rather than delete files (and not in preview), so not clear which one is (e.g here both the kept and deleted name have same name)
e.g
There are 2 songs with the Heartbreaker/Wishing Well 6b26cde8-9061-4992-9897-dea43065b240 key
Keep E:\JBM2\Free\Heartbreaker (1)\01 - 01 - Wishing Well.mp3
Moved 01 - 01 - Wishing Well.mp3 to E:\dels\01 - 01 - Wishing Well.mp3
Done, shows shows full path.
