.rsrc files?

Just curious about these files. Is it absolutely necessary to include them in the .component bundle? My AudioUnits scan and validate fine without it. When I leave it in, auval list my AU twice. Note that my AudioUnit is a bit of hack job because they get dynamically created from my main app. auval listing plugins twice is not something I see with a standard AU project.

[edit] removing the AU cache got rid of the issue of auval listing plugins twice, but my question remains, is this file necessary?

You can ditch rsrc if you have no interest supporting older hosts.
Waves from what I saw ditched rsrc. This makes old hosts such as WaveBurner and old versions of apps such as Ableton Live not see the plugins. All modern hosts won’t care.


Good to know, thanks.
