From the developer:
FileBox enhances Windows by adding several advanced functions to the standard Open File and Save File dialog boxes. FileBox adds two handy buttons to these standard dialogs. These appear on the right side of the Windows dialog box title bars. These buttons appear next to the minimize, restore, and maximize buttons with which you're probably already familiar.
