windows - How to start/open a file/folder that contains space in its name through command-line?

I'm trying to use the start command in the command prompt to open files and folders, but I'm unable to open files and folders that contain space(s) in their name.

I have tried the following queries (testing on C:\Program Files):

start C:\Program Files
start C:/Program\ Files
start C:/"Program Files"
start C:\"Program Files"
start "C:\Program Files"
start "C:/Program Files"
start C:/Program_Files
start C:/Program%20Files

But none of them work.

Answer

You would use:

start "" "c:\program files\"

That is because the first parameter is used as the title of the window, and is oddly enough, enclosed in double quotes.

Edit:

Here is a source about it: SS64

As an example, if you just type start "title" it opens a new cmd window with the title "title" in the title bar.
