Shared file storage between node red and HA?

[PlayedIn]

Is there any common file storage that is shared between Hassio and the Node-Red addon? A HA automation downloads and overwrites an html file every 15 minutes which mainly consists of a table of data (local traffic accident incidents) from a state gov website.

I want to access the html file in Node Red and modify some of its formatting codes before writing it back to use in an iframe card.

Is Hassio’s file storage completely isolated from the Node-Red add-on’s file storage? If so, is there a different way I could pass the file contents to Node-Red which could be passed back to HA and written to a file for the iframe card to use?

I don’t know about the add-on, but it’s super easy using regular docker (not hassio)
