Where are my custom presets?

Hello,

I created some drum patches for H5. When I go to Save, the screen for categorizing the preset comes up, but I don’t see where I can choose a directory to save my presets. How do I locate my presets?

Also, I created these sounds using Nuendo 6. If I delete my Nuendo 6 project, where I designed these drums sounds, will I lose all of the presets?

are you on WIN ?
if so see there : C/User/Documents/VST3 Presets/Steinberg MediaTechnologie/Halion 5

Thank you. I will check it out.
