Backup Media Files in DL2

Hello! I need to make a backup of all the media files in my DL2. I need all the pictures and videos in a dvd.
I have tried to make a backup using the Create content archive, but it creates a .DLC file. I need to be able to open the pictures and videos in other computers, so the .DLC file is no good.

Is it possible to make a back up of all the media files in the original format (.png, .jpg, ...)

Many thanks
