Kontakt 5 creating huge amount of 'system files'

CharlieW

I've been converting a load of old .gig instruments to .nki in K5 and saving to an external drive. I've noticed my Mac now has 600GB of 'system files' that is growing the more I convert. I haven't been able to figure out where these files are located and how to get rid of them to recover storage. Any thoughts would be gratefully received.

Thank you.
