When image files are moved from one folder to another and the source folder becomes empty, Photoshop Elements Organizer no longer shows the existence of that folder. This can cause a build up of empty folders in the photo archive area. It can also cause confusion and extra work if for some reason a user wants to move photos back to that folder. Since the folder name isn't visible the natural course of action is to assume the empty folder was deleted and try to create a new folder with that name, but that operation will fail with an error message presented. Once the user figures out what's going on he/she has to take another application and delete the empty folder, then go back to the Organizer and create a NEW folder with the SAME name. The folder will then be visible for a while and he/she can move files into it. If for any reason something else is done that significantly changes the state of the Organizer, the newly created empty folder will no longer be visible. I reported this problem several years ago and nothing has been done. To me this is an example of a poorly design UI behavior that should be fixed. Unless there's something really strange about the product design, this should be extremely easy to fix. There must be a logic check made to detect an empty folder and not display it. Just remove that check. Another solution would be to delete the empty at the end of file move operation.
