Jupyter Notebook Workspace
Udacity offers Jupyter Notebook workspaces as required in the classroom.
Each Workspace is a Linux container with sufficient computing resources, a pre-installed Python environment, and packages necessary to execute the exercises and the project.
Upload, Download, and Delete the Files
You can upload, download, or delete files as necessary. If something goes wrong, you can restore a backup or reset the entire Workspace to its original state. The screenshot below highlights that you can duplicate, rename, move, download, or upload a file.

File Editing
You can work on the existing files or add new files as necessary for the exercise you are working on. Make sure to save your work periodically. The screenshot below highlights creating a new Terminal in a Jupyter Notebook workspace. You can create any file type, as permitted, in your workspace.

Working within a Notebook
You can use all of the features available in the Jupyter Notebooks, such as writing and debugging code, analyzing data, and visualizing results.

Refer to the official Jupyter Notebooks documentation to learn more about the basics of a Notebook.
Saving additional files
Store all your files in the /workspace directory so you can still access them after a Refresh. Any files stored outside the /workspace directory will be deleted after you RESET the workspace!
Recommendation while working with large files in the workspace
Do not store large files inside the /workspace directory. Otherwise, it will hang up in your workspace the next time you visit. Keep the total contents of the /workspace directory to 3 GiB or less, and do not store any individual files larger than 1 GiB. You can store logs or checkpoint files in /opt directory. However, /opt directory will also be deleted after you RESET the workspace.
Troubleshoot
If you are facing difficulty with loading certain files, you can check the current directory size, as shown in the screenshot below. The overall size of the /workspace directory must not exceed 3 GiB. Always delete the unnecessary files and folders. You can check the current directory size and list of files as follows:
cd /workspace
du -sh
ls -al
