Display a nested directory/file tree on a Confluence page, similar to Windows Explorer

[Daniel Miller]

Given a nested hierarchy of directories and files (the data only, with no access to the actual system), I'd like to generate a display similar to Windows Explorer, with each directory level expandable and collapsible. Such displays could include up to 25K files. I'm aware I might be able to do this with nested Expand macros but this seems ugly and wastes a lot of vertical space. Is there a better way? Thanks!
