Hello PittsburghEng
I think that It's the MS-DOS file name you're looking for. When a name is too long and the beginning is the same, only the ending changes ~2 ~3 etc. If you're still using an older system you should be able to see the MS-DOS name by using CMD and using C D to get the directory in question and then typing DIR. I have Windows Vista and I don't see the tilda anymore. PS ( there's no space between C D )
