Clearing Unused Media in 10.1.1. Is it possible?

Hello!

Prior to the release of the new Library system you could copy events/projects and select an option titled "Copy only used media", then simply delete the old Project/Event to solve this problem.

With the library system... I'm stumped. I read somewhere you could assign a Keyboard Command to the "Show Unused Media" in the browser, which sortof works... but it still won't let me delete this media without saying it's in use.

Has anyone cracked this code?

Make a new library. Drag the project into it. Only used clips are copied.

Tom, you're a saviour across all message boards. Thanks!
