Hi Hunter,

FileStore is a special folder within Databricks File System (DBFS) where you can save files and have them accessible to your web browser. In your case it the png files will be saved into /FileStore/plots which contains images created in notebooks when you call display() on a Python or R plot object, such as a ggplot or matplotlib plot. If you delete files in this folder, you may have to regenerate those plots in the notebooks that reference them.

If you would like to download the files, then you will need to follow the instructions from here to create the url https://docs.databricks.com/data/filestore.html#save-a-file-to-filestore

Thank you.
