batch file - How to use spaces in "if"?

Question

I'm trying to see if a string is the same as another string by using if, but the string contains spaces!

It looks something like this:

if %DriveDir%==NOT BOOT FILES echo Working

Simply put, it says "BOOT was unexpected at this time"

if %DriveDir%=="NOT BOOT FILES" echo Working
if %DriveDir%==%nbf% echo Working

I have tried using quotes and storing the string in a variable like this, but nothing changes.

Answer 1

You should also add quotes to variables.

if "%DriveDir%"=="NOT BOOT FILES" echo Working
