Protected Files

[Tricxta]

I would find it really nifty if we could place a lock on certain graal files, meaning people no matter what can't upload over them. Such files such as the:
ganis :sit,walk,idle,swim and bla bla bla
sounds:hit,step,etc
images:basic heads and shields

Or.... a better idea would be so everything needs a prefix to be accepted for downloading.

I'm suggesting this because I tired of having to repeatedly replace files, and I'm sure others are as well.

Got a reason why this shouldn't be implemented? I'd like to hear it
