No, I was referring to the way the Mac is standardly set up (i.e. with
a case insensitive file system.) If you have formatted your disk to
allow case sensitivity, then it will work as you describe, so you can
have two different files with names that only differ in case.

Yes, this is correct. If the file system doesn't distinguish case, it
can't know the difference. This is why I don't format my disks this
way, since it can lead easily to the situation you describe.

Well for me, the above concern is definitely a disadvantage.
