You can search more than one drive at a time using an undocumented feature of Find by separating the drive names with a semicolon. For example, if you want to search your C:, D: and F: drives, type C:;D:;F: in the Look In box.

The Find utility uses some unique, and undocumented wildcard capabilities that you can use in the Find dialog's Named box. For example, use a question mark to replace each unknown letter or number in a filename. Each question mark must replace exactly one unknown character, so you have to know how many characters are in the filename. Each asterisk, on the other hand, can replace any number of unknown characters. You can use combinations of question marks and asterisks to refine your search.
