I have one MMC/SD card, I want to keep some contents on the MMC card to be write-protect, and not be copied illegally. The other capacity of MMC is used optionally.
SanDisks comes with right protections which you can use to protect ur data..
there are softwares which comes along with the media which helps to hide the filex which u want to.. unless or until u run that particular protection software which wud encrypt the data , u wudnt be able to use or make changes to these files.
