You should no longer need to ever run Tidal once Roon is setup. Roon just accesses Tidal using your Tidal credentials - everything should be selected and played from within Roon. If you like a Tidal album then just add it to your library from within Roon and it becomes part if your Roon library. Any music files on your harddrive will add automatically upload to your Roon library provided they are in the designated folder(s) you setup in Roon.
Roon does nothing to affect your harddrive music library - it does not move musuc around. However you can delete music files if you wish - Roon will warn you if you try to delete albums or tracks because this is permanent.
