I think am slowly getting it.
Another thing, when trying to create a shortcut for the 'File Rescan' we are talking about now, I found two shortcuts which seemed appropriate:
- File: Scan folders for new files
- General: rescan file tags
If I am correct, the first one will do a complete library scan [Ins]
The second one seems to do the job, but then the naming is now a bit misleading?
