Any way to see a "drive location" column for source media clips in an event?

...other than looking at library properties?

You set the storage location for clips at the Library level, not in the Events.

If you need this only occasionally the only place is the Inspector (what I think you call the library properties).

If you need to really dig through your footage I highly recommend Producers-Best-Friend:  www.intelligentassistance.com/producer-s-best-friend.html

You export a xml of your Library or Event(s) or Project(s) and will get all the information you ever hoped for. Genius piece of software. Not cheap but it can do it all. And the best thing is that their support is second to none as every time I asked if it could report on 'XYZ' they added the function (if it was in the XML of course).

As said, Producers Best Friend, or use Final Cut Library Manager.

Yes I know, thanks. Was pointing out differences to avid editors.
