Try doing a search with hard drive option and put A wildcard "*" infront of the title(s). If you do a system restore try going back at least two "restore" points. Also, try a search through your command prompt and use the appropriate strings/variables to locate the files. do a help search to list all the string/variable arguments and find the one that matches your issue. Search the whole HD not just the windows directory. Use a /p or /w to see the progress page by page otherwise it will scroll faster than you can read (unless you are DATA (Bad ST ref) or if you were, you would have solved the problem). Best of Luck
