FileSwitch wildcards to lowlevel?

I had a quick go but every request came through to the FS without wildcards, doing directory enumeration itself. If so some examples of things that will make it through would be appreciated!

There are two ways of doing so: ● by adding a module that FileSwitch communicates with directly ● by adding a secondary module to FileCore; FileSwitch communicates with FileCore, which then communicates with your module. Perhaps this may explain the difference?
