Assuming that C=source drive and D=destination drive (both HDD), and the source file=srcfile.ext, in the folder C:\source, all you would need to do is load the comp into DOS and type "copy C:\source\srcfile.ext D:\srcfile.ext", and it'll be in the root of drive "D". Of course, if the file's name is longer than 11 characters (8 name, 3 extention), then it would be -- [first 6 letters]~1.[extention]
