function MatchesMask(const StringToMatch, Mask: string): Boolean;
Returns True is a string value matches a format specifed by a mask.
The function raises an exception if the Mask parameter is syntactically invalid. Syntactically valid Mask consists of literal characters, sets, and wildcards.
Wildcards are asterisks (*) or question marks (?). An asterisk matches any number of characters. A question mark matches a single arbitrary character.
The comparison to literal characters is NOT case-sensitive.
