Hey both of them were really interesting tricks but i think using illegal characters is better.I`ve been able to rename some folders to nul,com1,etc by unlocker but it doesn`t accept :,< and etc. one more thing, I have used some disk editors like Winhex to do that and it worked but even if you rename it again to a legal name, it says that its not accessible!!! Does anybody have any idea or something????
