How can I recover a form that was deleted?

It seems it would be simple to ruin several hours of work by inadvertently deleting a form. I notice that there is not even a delete confirmation. How do I protect a form from being inadvertently deleted? if a form is inadvertently deleted, is there any recovery method?

If you delete a form accidentally, you can retrieve from the Trash folder by opening the folder, selecting the form and clicking on the Restore button.

Unfortunately, there is no way to lock a form to prevent it from being accidentally deleted. But, as mentioned above, this shouldn't be a problem since it will only be moved to the Trash folder. Please note that if the Purge button is clicked, then the form will be permanently deleted from your account and it won't be possible to recover it.

Let us know if you have further questions.
Thanks.
