I often back-up large numbers of files onto DVD's (as well as storing on external hard drives). Many times, the folder contain more than the 4.7 GB which fit on a DVD. I find myself dragging the files to a burn folder and then guessing by remiving files and checking the folder size until I reach a limit that is small enough to burn.

Obviously, this is quite tedious, and since my mac seems to be able to do most things very easily and intuitively, I thought there may be a way to go into a folder with numerous files and automatically select say 4.5 GB worth. Anyone know if this is possible, or if there is at least a better way of trying to do what I'm doing??
