Storage

Do I need to purchase additional storage?

Not at all. You have plenty of storage available with 100GB . And you can always delete or transfer the old files you don't need. 

Does Boomcaster automatically archive or delete files?

Not at all. 100GB is sufficient for most users, When  you approach the available storage limit, you will start receiving notifications. You can also track storage utilization under Account...

How much storage am I using?
