When you do a dir do you see the space?
If so, does it look like "director y" or "dir ecto"? If the first, its actually a directory with an extsion, to access it type "cd director.y" The second means a trick was used to get a space in there. One method was to use a null character that looks like a space, to get past that type "cd dir"<alt-0>"ecto" note: you have to hold alt and press 0 on the numeric keypad.
If those don't work, and you do see the space using dir, I have some more tricks that I know.
You might want to give a directory listing so we can tell the directory you're trying access. type the command "dir > it.txt" and paste the contents of it.txt to here.
