Wildcard Search
See Also
Allow you to use wildcard characters to search one or more file(s).
In the wildcard characters, the interrogation (?) represents just a letter and the asterisk (*) is a wild card that stands for any combination of letters.
For example, to search a file named "index.txt", you can type the wildcard characters like *.txt, in???.* or ??*.???.
