If I recall, the pendulum has swung - years ago, there were complaints from users who deleted files from their hard drives inadvertently thinking they were only deleting tracks from their Roon library. They argued that Roon should do more to make this difficult to do accidentally. Here’s a thread that includes some posts in which forum members are quite surprised that Roon actually deletes local files when you tell it to!
I’m guessing that the Roon team would rather field complaints that tracks are a pain to delete than a pain to recover after deleting them unknowingly! Cheers!
