Halion 3rd party presets tags

Hi all,
My question is - I have tagged and added various data (moods, categories etc.) to a bunch of presets in a 3rd party library I bought and installed via library manager. Now I would love to back up all this metadata - my question is, where is it stored and how can I do that ? I checked the last modified date of the 3rd party library .vstpreset file and it`s been few years so Halion doesnt modify the file I guess… where is the metadata then ?
Thanks !
