How to use the ImGuiFileSystem?

THis here: https://github.com/Flix01/imgui/tree/2015-10-Addons/addons/imguifilesystem

How do I use it? I looked through the source and tried to use it but no window comes up. Either I’m missing something on using it or it doesn’t work anymore.

Hello,
Please ask in the Issues section of said project.
