I think this is a symptom of the fact that Windows is (and always has been) case insensitive. It will allow you to name a file "test" or "TEST" but wll not allow two files in the same folder, one named "test" and the other "TEST".
I've encountered the "problem" described by the OP and the only solution I have been able to come up with is to rename "test" to something completely different, for example, "est" and then to "TEST".
