If I understand correctly:
* You installed MusicBee, which added your existing tracks to its library
* You deleted a heap of files in Windows Explorer
* Now you want to remove those (now) missing files from MusicBee?
Two ways to do this:
1. Manually:
File > Rescan / Add files with
Remove dead links checked.
2. Automatically every time MusicBee starts:
Edit > Preferences > LIbrary Select
Check for updated files and
and remove dead links at startupIf I've misunderstood, then
.
Bee excellent to each other...
