I have an external drive connected to an iMac and the drive contains a Time Machine backup of another Mac. I'm trying to find a Light Room catalog on the external drive so I can manually drag it to the iMac. When I press Command + F to search the drive, it is only set to search the iMac. 1. How do you I change the filters in the find window so that it only searches the external drive for the file I'm looking for, or maybe the entire Lightroom folder? Thanks!
