Renaming Node.js folder name

So actually I just started to learn web programming with node and express. I created a folder named "Node Web" inside my programming folder and do npm init in it. Right now, the web is already deployed in heroku. The question is I want to rename "Node Web" folder with a new name. So I tried renamed it from vscode explorer but I got this error

Error: Unable to move 'Node Web' into 'Programming'(Error: EBUSY: resource busy or locked, rename 'd:\Programming\Node Web'->'d:\Programming\New Name')

How to fix this?
