In method 4, Reallusion introduces a new pilot Content Downloader for all content lovers. By adopting the new universal file format (.rld/.rlcontent), you may now get any content whether from the Content Store or the Marketplace. We keep your purchased content online to let you be able to check and manage them anytime. With the Instant Content update feature in the near future, you will receive instant notifications whenever your purchased contents have been officially updated; allowing you to always enjoy the latest content on time!

This method is still in Beta test, if this method can't work in your case, please revert to other methods.
If you can't see any content in this folder, please register your iClone 6 serial number in your member page or log in your member info inside iClone 6.
So, the order history of the content packs will be recognized to display your purchased items.
