Inquiry Regarding Box Business Trial Features

Dear all,

I am currently on a trial period of the Business plan, and I have a few questions that I need clarification on:

1. Does Box support a "free up space" function (allowing files to be stored only on the cloud while freeing up local storage)?
2. What is the maximum file size I can upload?
3. Can I change the default storage location of Box? (Currently, it is stored on my C drive.)
4. If I decide not to continue using the service, can I remove my credit card information from the account? I noticed a "Remove Account" button—does clicking this mean that the account will be deleted along with the stored credit card information?

Thank you!
