Well there are two points, firstly as my colleague said drag and drop is basically a file move as against a file copy
With Cut and paste of course if the - copy to paste is corrupted the file has gone with the cut.
Dragging and dropping from one folder to another on the same logical partition (both folders reside on lets say the C:\ drive) is actually a file move not a file copy, but when dragging and dropping a file from a folder in one logical partition to another folder on a different logical partition (moving a file from C:\ => D drag and drop will perform a file copy proccess. while copying and pasting will always be a copy and past process.
That said, I would just backup the whole of the folder, to DVD, you do not have to do anything except commence the process and insert the next DVD when asked for.
