I used to keep running into many individuals, back when I was working in video creation, who hurled away their old movies after they got them changed over to video production service. since why keep the movies, when a tape is so much better, isn't that so? A great many people lived to lament that, particularly when it came time to change over to. Unless you're exceptionally certain that you've extricated each and every piece of data from those tapes that you will ever need, and you're certain it's really exemplified in the new arrangement, I'd keep them. Be that as it may, that is simply me, and I'm a conceded accumulator.
