What is the crowd's opinion of KGB Archiver?

From 3.5 billion comments

it mainly works on video stuff though (hence why a video game can be compressed like crazy using these sorts of programs)

http://sourceforge.net/projects/kgbarchiver/ , you could always try to bribe people into using this more often :P

Mate, that would be awesome and much appreciated. I'm unsure how small you'd be able to get it, so depending on how small it ends up i may still have to download in two goes using two different months data allowance. We're already at 40gb this month :/

Another month and a half and I will hopefully get unlimited (if it's available) when I move towns, but my dl/ul speeds won't be nearly as good as they are here on my 80gb plan.

Edit: Also, feel free to use whatever compression you want, I'm pretty sure KGB is the best available, but it also takes quite some time - You could be looking at 2-3 days for the whole 60gb, so maybe try it in 5-10gb blocks? It doesn't matter if you can't do the whole thing, but anything I don't have to download uncompressed helps. If you want to use KGB, then you can get it here and download the .msi one
It can be a little confusing to find the download through google.
