Hi, The responses I am getting regarding my last post concerning DOS file and directory structure are not quite what I was looking for. Here is a clarification of my requirement. I am looking for an example (preferably in C) that implements a DOS directory and file structure suitable for use in conjunction with a PIC16F876 and FLASH memory. (ie. I want to write files to the FLASH memery from the PIC and view, move, delete etc as you would in DOS on a PC). TIA Regards David Huisman -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
