Hi,

"...50GB data every 60 days.Once processed, I split the data into several directories which is normally a DVD image size..."

OK, so you want to fill dir1/... with up to 4.7GB of data from a given directory, then start the next "DVD" aka dir2, fill it up again and so on? Is that what you are after?

"...script that will check and display each subfolder size..."

this sounds like something to start with. Do you want to share your snippets?
The problem will be to properly fill up the directories. Another question: why does it need to always be the same folder structure. I mean, you could start with dir1 and just fill files into dir1/a or so until you either hit the 4.7GB limit or have no more files in a, then move to b and so on. If d is "full", then move to dir2/a and so on...
Sounds reasonable?
