File Storage - Pooled or individual?

File Storage - Pooled or individual?

I have a Zoho Creator account, Professional Edition, with 5 paid users, I should get 1GB / user for File storage = 5 GB total for our organization. If I do all of the file uploads for my account (no one else does file uploads), am I able to use all of the 5Gb myself, or is it tracked individually?
