My zoho docs folder on my desktop shows files totalling 16gb, but in the admin folder of zoho docs it shows I am using 49gb of my 50gb limit. My personal folders are shared with 2 more users, but their storage used is minimal. Why am I using so much space?

Secondly, what is the difference between sharing my personal folders and using workspaces to share documents. Would this less space?

Thanks

Paul
