Introduction
In this module, you'll learn how to work with external files. Microsoft Dynamics 365 Business Central is a software as a service (SaaS) application that doesn't allow you to access files on the server or the client side directly. Therefore, you need to use streams.
Additionally, you'll learn how to use the File object with its stream functions to read and download a file.
Along with the File object, you can also use the extra functions in the File Management codeunit that will help you with managing files in Business Central. This module will also introduce the Temp Blob codeunit that can help you convert streams.
