If I may....
I am aware of 2 major ways to help clean up missing links in your database resulting from files you deleted outside MC.
1 - You can create a smartlist that will list your missing files:
- View->Add View->Add Smartlist... or F9
- add the following Custom rule: [=IsMissing([Filename])]=1 (see screenshot)
- Name your smartlist with some sensible name
Now you can select the missing files and delete them from MC database by hitting the delete key
2 - A more interesting and automatic way of cleaning your DB is to setup auto-import folders
- Tools->Options->Library & Folders->Configure Auto-Import
- Add your current folder(s) as auto-import folder
- Tick the following options in the Tasks section: "Update for external changes" and "Fix broken links (protect files on missing drives)"
This way, your database will be automatically cleaned up and will follow any modification done outside of MC
Hope it helps,
cheers,
