Change the directory one folder at a time(instead of
cd C:\Users\Ajmal .M\GitHub\Open do: cd Users->
cd Ajmal .M-> cd GitHub -> cd Open).
Also make sure there is no space in your folder naming.

# If the directory you want to go to contains spaces, you should not give it an argument directly. The command below will generate error.
cd test directory
# Instead write it in the form of a string
cd "test directory/..."
