How to?

I have a bunch of off-line clips and (because I deleted files from the disk) and many clips not used in all timelines that I've created in my project.
I can't find a command that says:
01) delete unlinked clips
02) delete unused clips
Resolve Studio 15B5 - Windows 10
Can't find and answer on the web.
regards
