Which grasshopper file format should I use?

Which file format should I use, .ghx or .gh? What do the rest of you use?

Here’s a summary by @DavidRutten

Thanks RM, I actually hadn’t taken the time to learn this difference until you asked the question and @stevebaer pointed out the explanation! I always use GH personally since I only ever make changes to the files directly in GH.

Thanks for the info Steve I guess I’ll start using the .gh type up to now it;s been .ghx

*.gh has been the default format for a while now. Though if you open an old *.ghx file it will of course maintain the format when saving.
