This method displays the Find File dialog box, which allows the user to specify a variety of criteria by which documents can be queried. This is the same dialog that is displayed when the user clicks the Advanced option on the Open File dialog. Queries can be specified by property set values and by document type. Regular expressions are supported when specifying a search criteria. The FindFile method returns the name and path of the selected file. If the dialog box is cancelled, FindFile returns False.
