Copy spanning multiple DVDs

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,

I want to write a script that will copy a source directory tree into a new directory tree structure that will be ready to be burned to DVD. Something like DVD1, DVD2, DVD3, where each directory is limited to 4GB. A program like burned to the brim would be perfect except it windows based and I need something that is platform independent. I looked at the cpan modules and File::Copy::Recursive seemed like a good starting point but it doesn't support limits by directory size. Before writing something new I was wondering if anyone knew of something available or a better starting module.

Thank you in advance!

Greetings Anonymous Monk , Had you Super Searched this topic you would have found nodes such as Burning ISOs to maximize DVD space and How to maximise the content of my data CD which should prove useful to you. Hope this helps. Martin	[reply]

Martin,thanks for the pointers to other nodes. I had done a super search but I used other keywords (copying, spanning). I hadn't heard of the knapsack problem. This is a great starting point. It actually nearly solves the complete problem. I love perlmonks, there's always something new to learn.	[reply]

In addition to marto's excellent pointers, you might want to have a look at my module, Algorithm::BinPack. I wrote the module with exactly this kind of problem in mind. You'll still have to do a bit of work, but the hard part (filling the DVDs as much as possible) is done for you.	[reply]
