I'm running Windows 7 x64 on a desktop PC. I download pictures, and rename them using the rename process in Windows Explorer. When I rename pictures in the folder, they'll have the name like pic (1) pic (2) pic (3) and so on. I can rename pictures until I reach pic (10001). At that point, Explorer no longer automatically increments them. The renaming status bar turns red, and an error message says: "The file name(s) would be too long for the destination folder". I am however, able to manually enter numbers higher than 10001, so I'm not sure what the error message is referencing.
Is there a registry entry, or environmental variable that I can increase the value to be greater than 10001?
