No, he wrote a program to squeeze these names through the system.
A user cannot enter names the system does not allow to be entered.

It might be, "*" is typically a reserved symbol for communication
between the user interface and the directory search code.
If the user interface won't let you do it chances are it is illegal.
If you don't know the answer to that try to copy an existing file
named say abc.txt to a*a, see what the error message will be.
(Sorry to the rest of the group, obviously everyone knows the answers
to that but it is not my fault we go there - and at the moment I
don't feel like letting it go just because someone is too pushy
with his nonsense).

Or do you mean that you would be wrongly labelled mental just because
you want to have the name written on your identity card to consist
only of hieroglyphs and special characters.

Don is a "user" as long as he uses the user interface. A programmer
and a user are not the same thing in that contest and please do not
go into more bollocks on obvious definitions like that.

While I don't know how this is done under windows I think you know that
even less than I do. Your above means claim that every application
written for windows has to prepare the name such that it will be a
valid one.
It is obvious that normal windows applications do not write their own
name validations, if some call allows writing an invalid name then
reading the OS manual will tell you that you must use another call
prior to it which validates the name.
You should demonstrate at least such basic programming knowledge
if you want people to take your posts as something more than standard
"always know better" babble by someone who does not really know what
he is talking about.

Ah, now you are trying to cheat your way out of the hole. No, I never
said that. I said that file names are ALSO for human consumption.

Try to spell over the phone a file name like "ThIs Is An eXamPle Of A
nAMe foR iDioTs".
Then come and repeat your claim that file names - or whatever names
which are represented in text - are to be compared case sensitive.

Or simply stop posting nonsense.
