I'm revisiting Zoho Docs again since your update but can't find out if its possible to share a folder publicly.

I have resources in a Google Drive folder that I share to my clients and I can place new files in whenever I want and they get shared.

The key thing is that they don't have to login or be a member of anything - I just give them a link to the shared folder and they can instantly view the contents.

Is this possible with Zoho Docs ?
