There are quite a few, but i can't name them or tell you them, i just know they are there.
If you do a virus scan with some virus scanners you will see that sometimes you get errors afterwards saying couldn't scan <file> because it is a compression bomb and this is a file that has had several compressions and if it unpacked it to scan it it would crash.
There was a thread in the avast! forums about one and someone was saying how someone on the forum had managed to get a 200GB folder and make it 20mb or so because they had compressed it with lots and lots and lots of different programs. It was an admin that postted it, so i am thinking it is pretty legit, but still boggles me that the files would still be usable afterwards
I know that doesn't give help, but it lets you know it is possible.
There is also a way that you can make your files sinto several .rar files and they are all the same thing, so you could have say file-1, fiel-2, file-3 etc all the way up to files-40 for example, each on say 40mb and they all have part of the same file/folder. When you extract one, it would know that each contained a little part and extract them all, so you would have the file/folder in several different .rar files, as soon as you unrar one, it unrars the all and puts them together. That way you could use one or two DVDs and then put it all back together when you have the stuff where you want it
