is it possible to compress a 4gb iso to 500-1000mb using winrar or something???
Depends what is in the ISO. An ISO is just a CD or DVD image. If the DVD contained compressible data, yes, eg lots of old-format BMP files, maybe you could compress it that much. But real-world ISOs tend to be full of incompressible data such as program code and/or multimedia content.
Data compression programs are not magic wands, and they work best on data which contains a lot of redundant information. Game or DVD ISOs do not contain much of that.
Think about it. If Winrar was a magic file shrinker, all content would be compressed down to 1 bit, and you wouldn't need DVDs at all.
Separate names with a comma.
