How to handle space in file name in any Linux terminal

Today I wanted to mount My Passport External Hard disk and it reminded me of how I used to be nevrous whenever I wanted to do any operation (copy/move/delete...) on any file or folder with blank Space character in its name in the terminal , (we dont have this problem in graphical file managers)

Lets learn once forever , how to treat it here is the simple rule :

Whenever you see the space in the name you just replace it with "\ " without Qouation Marks .
for example this will NOT work in terminal

cd /media/My Passport

because it has an space in it , to make it work I add "\ " for each space but the following will work

cd /media/My\ Passport

and it works , I promise .
