DVD and CD uses
My family love to travel, and they enjoy taking lots of photo as they go.
I then become their computer specialist, always need to buy bunches of blank DVD and CD disks for them
Apparently, I use DVD for media a lot, cause a blank DVD has 4.7 GB capacity, I could just gather up photos, video that I need and burn.
However, it's a kind of waste, that using dvd-r to write pictures only, DVD allows us to write a lot but if we've only got a few, let's say 500 photos, and we would just need a CD-r.
Sometimes last year I was upset of using NERO to burn a photo disk, and the software wouldn't let me.
According on the popup displays that I "should" use a CD-r to write the media instead of a blank DVD.
so I learnt to store some CDs with me, just to in case I would use it.
