NO,you don,t have to open and save 6000 files.... Go to the locating where your files are(or browes with the open dialogue window in your program). Click on the view menu. Select thumbnail. Look at your files as thumbnails. That's It. I only told you about the resave in the event one or two did not show....but that should be a rare case. You will need to do this each time you go to your files,as you don't have "view thumbnails' set as default in your Windows.Not much else I can tell you. SWAMP
