Hey programmers!

I’m doing a project, and for the last few weeks I’ve been completely stuck on 2 criteria. Ive searched through both my books, royce/the ansi c progamming language. Multiple forums and still now hope.

The first one is that i need to read a 1 MB data array from memory and write it to the local COM port.

The second one is getting a file, in windows to save to USB without prior knowing the location of the usb.

If anyone could help me out, would be greatly appreciated!
