Get Folder Size from Windows Command Line

Question

Is it possible in Windows to get a folder\'s size from the command line without using any 3rd party tool?

I want the same result as you would get when right clicking

Answer 1

There is a built-in Windows tool for that:

dir /s 'FolderName'

This will print a lot of unnecessary information but the end will be the folder size like this:

 Total Files Listed:
       12468 File(s)    182,236,556 bytes

If you need to include hidden folders add /a.
