I am working on an app which requires the modification of hex values of files. I have two questions:
1. Does anyone know where I can find a list of hex file markers E.g. each segament in a JPEG file starts with 0xFF followed by a byte indicating the type of marker. So 0FFD8 is the beginning of a JPEG image.
2. I have noticed that whenever I modify some files like RIFF, when I run then they need to be 'repaired' (in VLC player) before they can be run. Anyone know why this happens and how I can overcome this problem ?
