The File menu in JupyterLab has few options for saving and opening files. The menu items do let one browse the file system and search for a directory. For example, the File->Open from Path... menu item only allows entering a file on a path relative to /jlab/root. Questions:
What is the location of /jlab/root. Is there a command that shows it?
I like to keep files with code in a subfolder of my Dropbox folder. What do I do if my Dropbox folder is not a subfolder of /jlab/root?
