What are iso files, and how do I open them?

@Richard
Here's an article previously published on Ask-Leo which explains how to change the administrator password when you've forgotten it.

Hi!
I downloaded an ISO file for a game. I want to play it, but can i do so without copying to a disk?

@Emma
Programs like winrar can unpack an ISO an in some cases the game can be installed from that.

Thanks for your help.
We just need to use WinRAR, WinZIP, or 7Zip to extract or open it.

So then can one do an iso of its operating system on a netbook that does not have a burner, and then share it to my other computer that does have a burner?

Thank you so much. 7-zip works so well
