Zoho Project Usage and Integration

Hi,

1. What level of integration can be expected between Zoho Project and Zoho Docs.

For example:

a. Is there a provision that whenever we upload the document in Zoho Project it gets actually saved to Zoho Doc. ?

and so on..

2. Can we create folders till nth level in Zoho Projects for effective management?

Regards,
