This chapter introduced a few new actions (Create folder and Copy file) for the SharePoint connector, a new connector to an external service (Dropbox), as well as the concept of expressions (or functions). Expressions can be used to further create custom content or extract content from entities by following the steps of a flow.
Using these new components, you were able to copy files internally between SharePoint sites, as well as copy them to an external service. Both types of flows (copying files internally and externally) can be used as part of solving very common business automation problems, and increasing your familiarity with expressions will help you make detailed flows with customizable data outputs.
In the next chapter, we'll shift the focus to creating button flows.
