I agree with that, but on the practical aspects, how often do you need to
have in the same folder all the following files:
- "test
- "TEST"
- "Test"
?
Also, as Marius pointed out, the FAT/Windows filesystem is case sensitive,
it just has an uniqueness constraint, so you can name stuff however you
want to, just don`t have duplicates because you will quickly make a mess of
yourself.
It's easy to use the above argument for various cases, however IMO our goal
should be to write useful software, and the features we are discussing here
are mainly targeting the users, not the admins. My logic tells me that
users are more interested in resources and not in resource names. ("potato,
patato" [1] - see the OP on same resource, multiple names because of
casing).
Thanks,
Eduard
