CD.. in command prompt is used to change the directory. In any case, if it does not work you should follow this step.
In command prompt(CMD) we use several commands, one is CD..
to go back one step.
C:\xampp\htdocs\CodeWeb
By using cd..
you got this:
C:\xampp\htdocs
Error message
The error message comes when you use the simple easy command cd..
which is to go back one step. And it shows the error like below.
'cd..' is not recognized as an internal or external command,
operable program or batch file.
Solution
Use the same command with a space after CD
Instead of using cd..
use cd ..
You see here a space between CD and .. (two dots).
