WinRAR compression

[Joe_Black40]

I want to ask you guys...i have some ISO files,games and and i want to compress them.One of them is about 6,5 GB.What smaller size i'm able to get and what are the compression settings for WinRAR?
Thank you.

ISOs are usually pretty compressed as is unless they're filled with empty data, in which case, you'll notice huge compression. But that's because they're useless, not because they actually work.

You're better keeping them as an ISO format, or if you really want to try compressing it, the max compression settings using 7z format... 7-zip's compression seems to be a heck of a lot better then RAR's is. (And yes, I've tried both. WinRAR compressed some of my files from 3 gigs to about 2.9 gigs, 7-zip about 2.85 gigs. Not a major difference but considering it was program that wasn't filled with any empty space....)
