Can you recover deleted forms?

Deleted forms are stored in the account's Trash folder. It stays there for 30 days before it gets permanently deleted. Forms that are automatically deleted that way and forms that were purged manually on the Trash folder are no longer recoverable. However, while the deleted forms are still in the Trash folder of an account, it can still be restored.
