1) When you record all 6 tracks for an hour, each track is saved as a separate (and very long) audio file.


2) If any piece of that audio file is in use, DELETE UNUSED will not delete the file. It doesn't trim off the unused pieces.


3) When copying audio the original files are still in use, the 788 can not delete unused of the original huge audio file. Thus, no space is freed up.
