I was working in Lightroom and I can't remember what I clicked on, but now I can only see the Catalog with 3110 photos but not the individual folders that they are/were in? What did I do and how can I can the folders back in that one catalog?
Try pressing F7
Expand the Folders panel by clicking on the panel title bar.
If you can't see it at all, go to Window > Panels > Folders.
It's fixed, thank you! I was going to add a new folder and somehow the folder panel was unchecked. Don't know how that happened but am glad to be up and running as usual! Glad you are all here to help before panic set in! -g- Thanx again
