did any of you guys know that this trick made trouble in the earlier vista home premium !
when you press the combination of alt+0160 ; the folder will be name less ! and untouchable at the same time ! there was a programming error in the earlier versions of vista ! the problem was , the folder will be unreadble , corrupted = no rename , no delete , no shift delete , no nothing ... corrupted data

.
back in a days in win 98 i used to use a diff method to lock the file :
for those who are interested in the old school method there it is :
1-creat a new folder on the desktop and rename it to "A" for example
2-open command prompt and jump to desktop VIA command : "cd desktop"
3- type the following : move "A" alt+254"A" ; no quotes and the alt 254 combo should show you a big tainted square
4- press enter and watch the magic

... the folder will be literally useless!
of course all of you guys is wondering on how to undo this command so there it is :
1- same like above except : move alt+254"A" "A"
/\-Note that spaces should be written in the correct value otherwise the command will be useless-/\.
Hope that this command entertain you

... cheers
