I downloaded an ISO file of a game. What is an ISO file and how do i install and run my game from it. It said to do something with Clone cd???
I am a newbie at this.

If it is a CCD/IMG/SUB then just burn it with Clone CD. However you should find out what settings are needed first, as they very depending on the protection and your hardware.

where do you put the file(iso)in clone is it in temp folder

Clone CD does not burn ISO files, use CDRWin, Nero, Easy CD, BlindWrite, etc.

Get nero.
Install it
Load it up.
When you get the pop-up 'New Compilation' menu thing click 'Cancel'.
Click 'File' > 'Burn Image..' > Locate your file using the 'Open' thing.
When you've found it click 'open'
Then click 'Write CD'

That should do the trick.
