function FileAge ( const FileName : string ) : Integer;

Description The FileAge function returns the last modified date and time of a file FileName.   There is no need to open or close the file - this function handles these operations silently for you.   The returned value is in a 32 bit partitioned format. Use the FiledateToDateTime function to convert into a manageable TDateTime value.   If the file date could not be found (for example, the FileName was invalid), then -1 is returned.
