Description The SetFileDate function sets the last modified date and time of a file.   Version 1 of this function takes a FileHandle parameter to indicate the file. This requires use of the FileOpen function, which is one of the low level file handling routines in Delphi.   Version 2 of this function takes a FileName parameter to define the file.   The file is searched for in the current directory.   The second parameter, FileAge is an Integer date/time representation that is used to change the last modified date/time of the file.   Use the DateTimeToFileDate function to convert a TDateTime value to this integer format. Related commands DateTimeToFileDate Convert a TDateTime value to a File date/time format FileAge Get the last modified date/time of a file without opening it FileDateToDateTime Converts a file date/time format to a TDateTime value FileGetAttr Gets the attributes of a file FileSetAttr Sets the attributes of a file		Example code : Display, update, and redisplay the last modified date of a file var   fileName    : string;   fileDate    : Integer;   newDateTime : TDateTime; begin   // Try to open the Unit1.DCU file for the current project   fileName := 'Unit1.DCU';   fileDate := FileAge(fileName);   // Did we get the file age OK?   if fileDate > -1 then   begin     ShowMessage(fileName+' last modified date = '+                 DateTimeToStr(FileDateToDateTime(fileDate)));     // Now change the last modified date     newDateTime := StrToDateTime('01/01/2000 12:34:56');     FileSetDate(fileName, DateTimeToFileDate(newDateTime));   end;   // Did we update the file last modified date OK?   fileDate := FileAge(fileName);   if fileDate > -1 then     ShowMessage(fileName+' last modified date = '+                 DateTimeToStr(FileDateToDateTime(fileDate))); end; Show full unit code    Unit1.DCU last modified date = 30/10/2002 15:16:22    Unit1.DCU last modified date = 01/01/2000 12:34:56
