How to change the working directory in Jupyter Lab?

Dear friends, I am confused about how to change the working directory in Jupyter Lab? I have tried “c:\mydisk”. But how to find the current working path? Thank you!

I belibe (and could be very wrong!) that the only available working directories are relative to where the jupyterlab is started for security reasons.

Which set of lecture notes have you been working on? Generally what I do is start jupyterlab in my cloned GithHub folder and then I get access to any notebooks I have been working on.

Thank you, Professor! I met the problem when I found there was a prerequisite command before running other code in a Julia file,

include(“modelA.jl”)

Do I need to change the working directory so that the file of “modelA” could be found? Thanks!
