Before I move my work over to the Tiger drive, I thought it was about time I burned some completed projects onto some good-quality DVDs. There's about 30gb in total. To save on disk space, I thought it might be best to compress the folders but which format will be universally and easily accessible in 5-8 years? .sit, .sitx, compressed .dmg... Which one would you use? Or maybe something else? Or maybe not bother at all?
