Sorry. Thought that the resource packs forum was the appropriate place to post as I wasn't asking for technical help, I was asking for a 1.12 snapshot compatible resource pack - I guess I was wrong.
Thank you for the help. I'm on Windows 10 using Notepad. Downloaded Notepad++ and will try it, however that brings me to another question; for a 1.12 snapshot compatible and hopefully 1.12 compatible when it's released pack.mcmeta file, what is the text I need to put? Is it:
"description":"My Resource Pack"
Got this off of gamepedia and says the '3' is for 1.11 - will this also work for 1.12 or do I need a different number?
