This question got lost in the demise of Elements Village so hopefully the helpful person whose rely I couldn't read there or someone else can help me here.
After a very laborious process of transferring all my photos from Photoshop Album on PC to Elements 13 on Macbook Air, via Elements 11 (13 wouldn't run on the PC), I now have multiple copies of all my photo files and am running out of disc space. The folders initially loaded into E11 on the MAC were restored to it's SSD. I had to do a backup and restore to move from E11 to E13 on the MAC, and I restored to a flash drive as I anticipated disc space problems. Now I need to uninstall E11 and remove the duplicate photo files and folders on the MAC SSD. What is the best way to do this without loosing connections to photos? Since E13 references the photos folders on the flash drive I assume it won't notice if I delete the folders associated with E11 on the SSD so can I just uninstall E11 and delete all the folders containing photos using Finder in one move, or should I delete the individual folders within E11 first? Obviously I don't want to end up with redundant legacy files and catalogues taking up valuable disc space.
I'm not a Mac user, but I don't think the question is really Mac specific.
1) Do you have a backup of the photos and the catalog from PSE11 on the PC? This would be your fail-safe in case something happens. Until you have a backup, I wouldn't start deleting anything 2) Uninstalling PSE11 is easy and shouldn't impact PSE13 or any delete any photos 3) I would start by deleting one folder at a time. Delete one folder, then make sure PSE13 wasn't referencing any of those files (you would get a "?" on the thumbnail in Organizer if you deleted the wrong version). Once you are comfortable with what photos can be deleted, you can start deleting more.
