This is a question for the iOS version, but might apply to others, don’t know:
I know I can swipe a song file and send it to the trash, which is great. But I don’t see a way to “empty trash” when I go into the trash itself. I also don’t know how get rid of excess snapshots that appear to take up too much space in the app when I check my device’s storage in the settings app on iOS.
I’ve learned to “save” a version of a song I’m working on with the original name and location so that I get an “overwrite?” request, that appears to save excess versions from building up. But what is the best way to work within n-Track without lots of versions of a song filling up my song files?
