Is SPIFFS used? How?
Is there a simple example of a program that allows a user to open a PDF on the AP?

By default, about 1.5 MB of the onboard flash is allocated to SPIFFS.

What do you mean by "open a PDF on the AP"? How would that work?

The AP is just a network access device. Even if you are referring to a web server running on the same ESP32, what would you want the server to send to the client?

For useful help, please explain the application this will have. That is, explain the problem you expect this to solve. Also provide the configuration of the various parts involved.

You can almost certainly get hero with more information.
