The number of files referenced in the library database file seems to only keep growing, without deleting no longer existing files.
For instance I have one library file that shows only 20,000 files in music library node. But if I run "rescan all files", the status bar says total number as 35,000. And if I map a new custom tag and make it rescan, it shows 150,000 files as total number while rescanning (if I look into the library file some of them are files that used to be in external HDDs that are no longer used).
How can I clean up the library file so that it only contains files currently in my library while removing all other files?
