File :: lastPosition - Last file position

The last file position is the position set when accessing the file the last time. Setting file position allows reading or writing data from/to a specific file position. Setting file position after end of file will increase the file size. Data filled in the undefined area after current end of file is undefined.
Return value:  Position in an area or file ( int64  )

The big position value usually refers to a relative position in an area or file.
