Hi. Looking forward to installing / testing this great app...
One idea that could be really helpful - comparing sessions / files in two folders of the same song. I have working folders of songs on one internal drive and a backup copies on external drives. It'd be great to check that both folders have the same files. This could be done before reducing the excess and / or after.

To compare files in folders, I've used
MSFT Sync Toy 2.1 in the past. Would like to see what you might do - as it could be better.
