How to remove a vstpreset

Hi, I don’t find the way to remove a vstpreset. I can save and load plugin presets but I can’t remove or rename them. Any hints? Thanks much in advance!

You should be able to do so by locating that vstpreset in MediaBay, from where you can right-click on it and delete or rename it.
Alternatively, you can delete/rename it in your computer’s file hierarchy, then go into MediaBay and rescan the folder from which you had just deleted/renamed it.
