Version history of your files doesn't take up any of your available storage quota.
Your version history time period depends on your account type.
- Dropbox Basic and most Plus accounts have up to 30 days
- Plus accounts with extended version history can recover files for up to a year
- Professional and Business accounts can recover files for 180 days
Note: The extended version history add-on feature is no longer available for purchase. Customers who previously purchased the add-on feature can recover files for up to a year after the add-on purchase.
