'Function to write the embedded DATAs back to disk. Call this FUNCTION
'once, before you will access the represented file for the first time.
'After the call always use the returned realFile$ ONLY to access the
'written file, as the filename was maybe altered in order to avoid the
'overwriting of an existing file of the same name in the given location.
'---------------------------------------------------------------------
'SYNTAX: realFile$ = WriteqbiconData$ (wantFile$)
'
'INPUTS: wantFile$ --> The filename you would like to write the DATAs
' to, can contain a full or relative path.
'
'RESULT: realFile$ --> On success the path and filename finally used
' after applied checks, use ONLY this returned
' name to access the file.
' -> On failure this FUNCTION will panic with the
' appropriate ERROR code, you may handle this as
' needed with your own ON ERROR GOTO... handler.
