No Quotes Required for Paths with Spaces

I got a comment back from a technical editor today that I didn't need quotes around the path in a CD command at the command prompt. I was surprised because the path included spaces. However, after testing, it's true!

In the past I would have done:

cd "folder1\foldername with spaces"

However, this version (without quotes) works just as well:

cd folder1\foldername with spaces

Since it worked in Windows 10, I tried out Windows 8.1. It works in Windows 8.1 too. It's funny the little things you learn sometimes.
