How to open files in cmd with non-standard programs?

Question

cmd/bat

For example, I want to open index.html with sublime text 3 instead of standard notepad. Windows 7

Answer 1

"C:\Program Files\Sublime Text 3\sublime_text.exe" index.html

Or, if you don't want to specify the path, put C:\Program Files\Sublime Text 3 in PATH and run sublime_text.exe index.html.
If you want even easier - create a sublime.bat file (anywhere) with the following content:

"C:\Program Files\Sublime Text 3\sublime_text.exe" %1

,
add the path to it (eg C:\Program Files\Sublime Text 3\) to PATH.
And you call:sublime index.html

Answer 2

start sublime.exe index.html ?
