how to take folder of XRNS and dump out list of plugins used in them

hi, how do i get a list of VST/AU plugins used in a folder containing XRNS files - without having to load all of them, one at a time to find out which VST/AU plugins are missing?

bonus question: can Renoise handle multiple copies of the same plugin (different versions) so that the AU ID is the same - as long as the filename is different (FusionFieldOld.component vs Fusion Field.component, f.ex.)?

Trying to get old songs to load with old versions of plugins… the new versions don’t support the same parameters etc etc.

Any help would be appreciated v much!
