Where are agents' samples on my disk?

Hello all,
currently I’m working on MPC as well as on Groove Agent (GA), therefore it would come handy if I could use samples from GA for MPC. In Mediabay I see that the samples of GA (or Beat Agent, better said) are wav formats. But I can’t find them on my disk. Are these normally accessable from a disk? If so, where are they located?

They’re stored in compressed .vstpreset files and can’t be accessed directly.

The only way to access them is by drag and dropping them from the full version’s Browser tab into Cubase.
