Wildcard Masks
Wildcard masks are patterns of special characters used to filter files/folder names or transfers. When a wildcard mask is matched against a filename, the two patterns are compared, letter-by-letter, from left to right until a mismatch occurs. If all the characters in both patterns compare positively, the filename matches the Wildcard Mask.
