Yeah but apparently now, the side benefit is that you can exploit the program and hide other programs and files, by appending $sys$ to the filename, or something similar. They are saying this is a boon to the WoW users against the Warden Software. Being able to generically use the hiding prefix on files, could be further exploited in multiples of ways, and might even been a boon to less suave script kiddies. I can see them taking this tech, and running with it.
