I wanted to post this in case others have the same problem with their wallpaper folders. A couple of years ago I had a problem opening my personal wallpaper folders through "personalize". It happened again today and i tried system restore to different dates, I googled and still could not find a reason for this. After reading a bit I felt it had to be software setting. I opened irfanview, then file associations and removed all the check marks, my folders now open. Would anyone know which association it would be. I know I probably need to put some of the check marks back in.
