A wildcard is a special statement that has an asterisk (*) and a question mark (?) to make a fuzzy match to a string (such as a file name, parameter name). When you look for a folder, you can use it instead of one or more real characters, and you often use wildcards instead of one or more real characters when you don't know the real characters or are too lazy to enter the full name.
