I have been running PSE 2019 and just installed the 2021 version. After PSE converted my catalog my file structure became totally flat (i.e., all my folders are directly under "Pictures" rather than embedded as I had them. This is a real pain because I keep images in separate directories associated with shot date and have "Raw files" folders underneath each date. Now I have a zillion "Raw file" folders and it will be impossible to sort it back out.
How did this happen and is there anything I can do about it?
Some additional information: this restructuring of my files is restricted to PSE. The tree structure still exists on my hard drive. Consequently, PSE now considers all of my files to be "missing files." What a frustration.
Unless there is a clever solution it seems like my best alternative is to just start a new catalog and reimport them. But then I lose all my tags, correct?
