only for deciving or fake copy
for example i have a file that another members can see it,if they want to copy them or ask me to copy it to their memories or flash or etc i cant reject them or say No! so such programs can save me!
ok,my English is not have good gramer!
1 - imagine that a flash memory connected to computer.
2 - a picture or any data was opened from explorer.
3 - in this level when i want to copy file to flash memory , data of file before copying i want it changes ( for example all bits converts to zero) then this ZERO file with same size goes to flash memory.
4 - when i want to go normal mode ( or go to fake copy mode ) >>> require password
im using registry code of write protection that it makes computer safe in copy,but it not protect my files againts DVD Writer
