A filesystem-like ContentsManager backend for Jupyter. This library allows you to hook up multiple file backends to Jupyter and interact with their contents using JupyterLab Filetree.

pip install jupyter-fs
jupyter labextension install jupyter-fs
jupyter serverextension enable --py jupyter-fs


Add the following to your jupyter_notebook_config.json:

  "NotebookApp": {
    "contents_manager_class": "jupyterfs.meta_contents_manager.MetaContentsManager",
    "nbserver_extensions": {
      "jupyterfs": true

Register additional contents managers in your jupyter_notebook_config.py. As an example, an S3Contents manager is added as follows:

from s3contents import S3ContentsManager
c.JupyterFS.contents_managers = \
    's3': S3ContentsManager

c.S3ContentsManager.bucket = '<your bucket>'

c.S3ContentsManager.access_key_id = '<your access key>'
c.S3ContentsManager.secret_access_key = '<your secret key>'

During application startup, you should see something like this in the logs:

JupyterFS active with 2 managers
Installing JupyterFS handler on path /multicontents

And in the UI, you will see your contents managers available: https://raw.githubusercontent.com/timkpaine/jupyter-fs/master/docs/example.gif

We can add additional contents managers:

c.MultiContentsManager.contents_managers = \
    's3': S3ContentsManager,
    'file2': AbsolutePathFileManager(root_dir=os.path.expanduser("~/Downloads"))

Here I utilize an AbsolutePathFileManager to grab another folder on my system for use. Remember, remote filesystems are still remote, and locally you may need to move around the filesystem with a os.chdir command (or equivalent in other languages).

Here, I have the above s3 and AbsolutePathFileManager, along with the original contents manager, for a total of 3 seperate spaces.

class jupyterfs.extension.GetHandler(application: tornado.web.Application, request: tornado.httputil.HTTPServerRequest, **kwargs)[source]

Bases: notebook.base.handlers.IPythonHandler


Returns all the available contents manager prefixes

e.g. if the contents manager configuration is something like: {

“file”: LargeFileContentsManager, “s3”: S3ContentsManager, “samba”: SambaContentsManager


the result here will be: [“file”, “s3”, “samba”]

which will allow the frontent to instantiate 3 new filetrees, one for each of the available contents managers.


Called when the extension is loaded.

Parameters:nb_server_app (NotebookWebApplication) – handle to the Notebook webserver instance.
