- yes VST2 does not support bundle, when you need to build VST2 plugins (Legacy) you have to adapt your postbuild.
- yes Windows does not support natively bundle like Apple does, that´s not a reason to not define/use such bundle (folder)
- why an end-user will or should delete some resources located in this folder ? this is the job of installer to manipulate such folder structure. If the user has the idea to move a plug-in, it is easier when all related files are packed into a folder (bundle)…
- which hosts do not support bundle on Windows? please give us more info, we will then contact them.
- VST 3 bundle is a good design, specifying and unifying cross-platform a way to organize resources (snapshot, additional resources (pdf, jpg,…), targetting different architectures,…)
Thx
