FM for get a PC File Name in a window

Hi

Does somebody can help me, i need to call a FM wich shows a window for enter a PC File Name (with F4 browse for windows).

I do not refer to FM 'F4_FILENAME' wich we use when we have a file_name field in screen and we use when user press F4 ; instead i need to call a window with the file_name field for the user enters the file name.

Doe somebody knows some FM wich i can use ?
