How do I store and retrieve documents in subdirectories of the configured documents directory in PrizmDoc PAS?

You can retrieve documents from subdirectories when dealing with local files. Simply pass the subfolder in the fileName parameter when creating the viewing session. You can test this by manually placing a document inside a subfolder and making the following POST request:

`http://localhost:3000/ViewingSession`

    {
        "source": {
            "type": "document"
            "fileName": "folder/document.pdf"
        }
    }
