Restoring Deleted or Edited Form Templates
You can restore form templates that you have accidentally deleted, or restore a previous version of a form that you have edited. This allows you to test new form layouts or update your forms without worrying about losing your previous form.
Open the Templates screen from the Forms menu. Next click on the menu button (...) at the upper right and select Backups.
On the backups page, find the name of the form in the list and choose the date you wish to restore. The system will make backups whenever you edit a form or just before it's deleted, so there may be numerous dates and times under each form.
The system will give a confirmation message when the form has been restored. Restoring the form will not remove it from the list of backups, and the form will be restored to the same folder it was in when it was deleted/edited with (Restored) added to its title .
Please note that you can also duplicate a form before making your edits.
