Take a look under preferences -> advanced -> miscellaneous and push the button 'Check the library folders for potential problems'. The function reports. It doesn't change/fix anything.
The function is also available in the the command line under calibredb. Try
Code:
calibredb check_library --help
This function is (obviously) new. It could find problems that aren't problems, and it could miss problems. Experience will tell.
