How to open project folder in sublime text via command line?

Question

cmd/bat

I created a bat that creates a project on the desktop (for example) the
sites folder:
index.html
--css
---style.css
--js
---app.js
I write in cmd like this: subl sites
but it opens sites as a file and it also saves sites without extension
, environment variables have been set, etc... everything works perfectly except to automate the opening of the project folder in sublime text 3 ...
How to do this ?

Answer 1

subl ./sites
