I’m running low on space on my laptop right now. I have a few .iso files which I want to compress. I know Magicdisc, WinRAR and etc can do some compression but they only compress by a few hundred MB. I want to compress a 6gb .ISO file to at least 4GB (3GBwould be heavenly).
Is there any kind of magic software that would do this? Paid or Free doesn’t matter.
