dvd-ram disks

i was givin three memorex dvd-ram disks, and am having one heck of a time finding the drivers for them. wanting to give them to my mother, she has WAY too much stuff on her puter and too many people using it….so would like to use these three disks for their music and pictures to elevate some of the clogging on her puter…. any suggestions as to where to find them??
