Interestingly even Windows explorer doesn't handle these odd files consistently. Renaming a file to "com1" is ignored with no error, though renaming to "com1.txt" gives an error about such a file already existing. Also, it seems that "com1.txt.txt" is not allowed either. I thought that the extension of "com1.txt.txt" was "txt" but it seems that it is "txt.txt" and so the base name is "com1" and thus not allowed.
