Zitat:Restricts the files displayed in the dialog box to those whose name matches pattern (all files). pattern (all files) does not restrict the directories displayed. The pattern matching in this function is similar to the matching used in matching wildcards in Windows and Linux file names. If you specify characters other than the question mark character (?) or the asterisk character (*), the function displays only files or directories that contain those characters. You can use the question mark character (?) to match any single character. You can use the asterisk character (*) to match any sequence of one or more characters.
