I worked with a file two days ago using the path:
I tried to create a new notebook, and it couldn’t find any of my files. So I opened the old one today, still runs fine. Tried pasting the same line in the new notebook and it can’t find it. Tried duplicating the original notebook so I could temporarily work around this - doesn’t give me the option any more. Am I running Jupyter on a different server or something? It shows all the right files from my computer in their expected spots.
