I suspect you are using Jupyter Notebook 7+?
If I go here and launch Jupyter Notebook 7.1 by pressing ‘launch binder’ and then make a new notebook file when the session comes up, I don’t see ‘Move’ as an option there.
Is that what you are seeing?
I think the idea was to streamline the options because you don’t have that in JupyterLab either and Jupyter Notebook is made on JupyterLab components. (You can see some of that discussion here, if interested.) You just drag and drop in the JupyterLab file browser to move and so maybe the thinking is you can move files in your system’s GUI?
You may want to read here and here for some other differences noted about the interface and links to more resources about Jupyter Notebook 7+.
