I really don't know what happened either. This has never happened with previous updates, and I have been a LR user since it first came out. This last time however as I stated, I updated per the notice, as I've done in the past and when LR opened, I noticed that most of the Smart collections weren't there. There is now only one. That is when I tried to consolidate some of the folders though the "G" drive, which is where I always import new images into. I make new folders through LR. After this update, I consolidated some images into new folders. When I didn't see these new folders in LR, I tried to re-import them. That is when I also noticed that the "G" drive was filling up beyond what was originally there. I also noticed that when I opened a folder, I didn't see images that I knew I had made edits to, didn't show any of the edits. The images just looked like I just freshly imported them. However, when I looked at the "All Photographs" - 12845 - all (most) of my edited, color/star flagged images were there, including images from folders that do not show up under "Folders" (from fig. 3). I still cannot understand why the "G" drive filled up the way it did. I consolidated images into new folders (example, multiple trips were put into one folder labeled "Trips") but that doesn't show up under Folders, (again fig 3). I did this to my years of attending the yearly Renaissance Festival under RENFEST and it is listed (long with all the sub folders). I did this to some other folders as well and tried to import them, but the drive was getting too full to except anymore, so I move those folders to a different drive altogether, but again, the "G" drive is still in the red. At this point I'm not sure what I can do other than to save what is left to another drive and remove LR altogether, re download it (I have the subscription), and repopulate it. and to start all over.
