In several places in µTorrent, wildcards can be used in place of normal characters in order to specify a pattern of characters that µTorrent should use to match whatever it needs. The following may be used in those situations:

Example: *File?A*|File?B* matches any file that contains File?A anywhere in the filename (where ? is any single character, such as a space or an underscore), or any file that begins with File?B in its filename (again, where ? is any single character).
