I had a nokia phone called Nokia TA-1235 for 5 years and i made way to watch videos from it from SD card i made a program that download and convert youtube links or playlists to the nokia phone to sell it for phone's shops and i need to make an SD cards filled with videos and the whole idea is that nokia phone is cheaper, smaller, stronger so i chose this specific type because it's comfortable and i want to fix some errors to be amazing and let it support java apps but i realized that it's not open source and the firmware is encrypted so i cant everything was good until i thought if someone's copied the videos from the SD card to another one he would destroy the project and i was thinking if i can disable moving files or add a code to the flash drive so when it get inserted into a pc or something else it would format it self or run a core on the pc so the SD card wont be shown there but i need a problem for MTP from the phone when it's connected to the pc so i need your help please, Can i run code on flash drive when it's plugged into an OS?
