It would be great to use a macro in Confluence which we could browse the content of a system folder without leaving the application.

Example of use case:
I have a folder "System test" that contains an entire html directory structure to display the test results. Normally I would put this in the htdocs directory of an Apache server and tell everyone what URL they need to access it. In this case we would be able to use Confluence instead, browsing that folder within a Confluence page.
