# Jupyter File ID Jupyter File ID is a server extension that allows for developers to easily track the path of files under the server root over their lifetimes, even when moved. Developers use Jupyter File ID by requesting a file ID for the file they wish to track. They can then resolve this file ID to a file path at any time to query the current path of that file. ## Contents ```{toctree} --- maxdepth: 2 --- user_guide/index ```
