Can Photoshop documents created with Photoshop CC be opened with Photoshop CS6?

I am contemplating getting the Photographer Package of the Adobe CC subscription. My question is, can folders created with Photoshop CC be opened later on, if needed with Photoshop CS6?   

I have recently retire but I own many of the CS6 Adobe software, including Photoshop. I have most of my photography hobby work created with Photoshop CS6. If I get the annual subscription for now, but later on I can not sustain the cost and suspend my subscription, can I open the documents created with the CC version with my permanent version of CS6 I hae instaled in my desktop?

I understand some features may be lost, but in general, can the documents be open and functional for the most part?

Also, I haven't been able to find if the Phogrographe's pagage also includes Bridge, or if this app requires a different subscription plan.

Your help in providing some guidance or clarification on these questions, would be greatly appreciated.

Thank you!
