I saw lots of responses, but I don't think anybody pointed out that the 
filename is probably invalid.  This particular string will work, but if 
you have a directory that starts with a T or an N, you may get some 
surprises.  The backslash is treated specially in a literal string.

When building a Windows directory name in a literal string, you 
generally need to do one of three things:

1) use raw literals
2) double the backslash
3) use a forward slash
