Calculator for filling data disc maximally?

by James4545 / January 24, 2017 11:37 AM PST

I was wondering if there was software that could show, from a set of data files of varying size, what assortment of which files would come closest to a certain total number. Say I've determined that my dvds will hold no more that 4.687 GB of data. And say I have a folder with a dozen or so files of varying size. Rather than guessing and adding/subtracting files back and forth to try to come closest to 4.687 gb without going over, if there was a program to tell me which combination(s) of files (identifying each file by it's size) would save so much time. Hope I've explained this correctly. Haven't found anything in numerous online searches yet.

Not really. Here's partly why.

Not only do you have to consider the file sizes but the file names could be long and cause a directory table to extend. So while you can google "BURN TO THE BRIM BURNER" there's a reason it's not usually used. The inexactness of the target file system and more. is a typical back and forth about this app.

I used such a program to copy a directory with files to the least possible number of diskettes in MS-DOS. It came from some download site, but I've really forgotten the name. Moreover, I doubt if it would work with GB's in stead of kB's.

Now with 64 GB USB-sticks and 1 TB external disks to copy to it has become irrelevant.

Thanks RP and KB. I suppose my question is more of a math problem than specifically a dvd or cd. If only there was a calculator that could take a bunch of varied numbers and spit out the results of all possible combinations of those numbers added together along with their specific combinations. It would still require a bit of work, entering each number, finding the ideal combination, etc. I've found that for dvd's I like to fill them with files that total no more than 4.687 gb (I always keep the total several mb below that just in case) and will get a successful burn, unless the disc is defective.
