These files contain the settings for the Nokia Maps software. The files also contain the version number of the software. You will commonly find the QF files stored as a plain text file in the root directory of the phone's memory card.
Because these files share an extension with the QF web page extension, it is important to make any modifications to these files carefully since the content being modified could corrupt the software or a web page.
