Best compression program!!!

[goku1234567890]

Can anybody suggest me the best compression program there is. I have a lot of files and personal data which i converted into a .iso file and deleted the original data. Now my space is filling up so i need to compress that .iso file. I heard about KGB achiever but it does not compress files bigger than 4 GB and my iso file is of 13.1 gb. Any help would be appreciated and thanks in advance!!! Another thing that i can pay for the software but it has to decrease the size on a major account!!!

Hi
Why a giant ISO file and what software did you use to create it?

Data files like .doc .xls etc for Microsoft office can usually be compresses but new format .xlsx & .docx are already compressed archives

.jpg & gift are already compressed

7 zip is well regarded and can open standard ISO files
But for different data types you may find different programs better at compressing them

Personally I would buy a new hard disk possibly external USB 3.0 + esata interface
Rather than trying to compress files and risk data loss

This a game folder that i converted to iso file using ImgBurn since my motherboard acting up on dvd rom and i can't install any game so i want to preserve any game i can until i figure out what is wrong with my motherboard (http/www.tomshardware.co.uk/answers/id-2174403/bad-sata-port.html). Till then i install games on my sister laptop and than transfer them to my PC using a standard ethernet cable but it is not a good one and transfer rate does not go above 11 mb/s. So basically i want a software compressor for 2 things:

1: To compress games which i install on my sister laptop so i can transfer them easily to my PC.
2: To compress games already installed on my PC to preserve them and make more space, and i don't have budget for new HDD right now.

best bet would be to install 7zip here : http/portableapps.com/apps/utilities/7-zip_portable
Install and open the program. Search for and click the iso file. id recommend the iso is on the desktop or easy to reach folder for this. click add. Click compression level to ultra. click ok
