How to delete all node_modules folder in system !!!

Most of the time once the project is completed, we will move to different projects leaving the old project folder in the system without any cleanup.

Nodejs application or npm based application node_modules will take a lot of system memory and eventually our system memory will dry up, its not easy task to find and remove all node_modules in one go.

Wrote simple CLI to do this clean that's "mo-clean", its a simple CLI that finds the all node_modules in the system by root path and provides the details like memory taken, last used time, and path. after getting all information it will remove those node_modules from the system.

Hi! I tried it on my mac. Installing Mo is fine, but it nevers stops searching, even if I point it to my Repos folder. Like /Users/david/repos

In your example you use the c: is that necessary?

Resolved the Linux related issued of the CLI, it's working fine on the Linux, I guess that should be fine with Mac as well.
If anyone used it on Mac please add comments.
