You are passing a string to os.listdir. (you call that string fileroot). There is probably something wrong with that string. In principle, it doesn't matter where you got the string from - with raw_input() or by hard-coding the string. repr(fileroot) is almost certainly not "C:\" -- that is not a valid string literal.
