Copy folder with progressbar

Question

Hi I have a function for copy a folder with a progressbar but on the big files the program freezes and the progressbar increases fastly (the progressbar increases according to the file's size). So i think make the copy in several part for the big files. Is it possible ? If yes how can i do that ?

See timers and threads at: http://www.c-sharpcorner.com/Forums/ShowMessages.aspx?ThreadID=69996 If I understand what you are saying then you can use a separate thread for the copy.
