Hey !
I am told the following in https://www.codecademy.com/paths/full-stack-engineer-career-path/tracks/fscp-setting-up-your-dev-environment/modules/fscp-text-editors/articles/visual-studio-code :
" 1. Make a development folder.
Navigate to a folder using your file manager or the terminal. Make sure it is a folder you visit regularly and will remember. Create a new folder called projects .
Mac users: This may be your User account or “Home” folder.
Windows users: You may want to save this on your C drive.
Linux users: You may want to save this in your User folder inside of the “Home” folder.
Inside the projects folder, create a new folder called HelloWorld . Everything you add to this folder will be part of your HelloWorld project."
→ Where do I create a “projects” directory : under the c or the d ? A friend told me I have to create it from my user directory and call the workspace, but I do not know how I can do that ?
Please could you hint me a little bit ? 
Thank you a lot !
Erwan
