I down loaded a folder from paint livery's. Then click on it to open it. a window popped up and it read, open with, and gave a couple of choices, I thought I did something wrong. I didn't know what windows uses to open files for down loads, so I choses note pad. My question is, How do I get back to what windows uses and not what I chose.  Thanks Stan

You're going to have to give a lot more information than that. Given the many formats that liveries can come in, it's impossible to tell you what it is you need to do, given that we don't even know what plane this is for.

Windows 10. I'm trying to paint PMDG planes. Using the Avsim livery libraries. I click a down loaded livery file, window popped up asking what kind of app do you want to open with. Gave a small list, internet explore, note pad, note book, windows media. I'm familiar with note pad. Clicked on that. everything now is a note pad instead of PMDG's little orange box. I see what your saying. I don't know windows well enough to say everything you may need to help. What I'm going to do is, put the paint texture with the note pad next to it and see if that works. I'll let you know.

Kevin I forgot to ask. I'm looking for Swiss air livery for new 747. I'd like to have that paint scheme  you have there, with my name on it. Is there link you can send. Are any of you guy's thinking about going to the Flight sim convention at, KBDL. Thanks Stan

Problem solved. Thanks for your help.
