This article describes how to restore certificates from an incremental backup folder on an old computer to a new computer.  


## Find the old backup files

:::tip
Read the [Save and backup locations](https://www.shineforms.co.uk/docs/save-and-backup-locations) for more details about the folders used by Shine Forms.
:::


Find the backup files from the old computer.  These will be in your Shine Forms folder, which is usually under your Documents folder in a folder named "**Incremental**"

> Documents\Shine Forms\Backups\Incremental

Note that it may have an alternative name or location if you set that up differently in your [save and backup options](https://www.shineforms.co.uk/docs/save-and-backup-locations).  It will look like this:

## Find your Shine Forms data folder

Find the Shine Forms data folder, which you can access by entering the following text into File Explorer and pressing Enter on your keyboard:

> %appdata%\Shine Forms\Shine Forms\Data\DB3

It will look like this:

Alternatively, browse to the following location (replacing all of the section **your-user-name** with your actual user name):

> C:\Users\your-user-name\AppData\Roaming\Shine Forms\Shine Forms\Data\DB3

## Delete all the current certificates

:::warning
You are about to remove all the certificates from the current copy of Shine Forms.  THIS CANNOT BE UNDONE.  Make sure you have [exported those to files](https://www.shineforms.co.uk/docs/certificate-sharing) or have taken a [backup](https://www.shineforms.co.uk/docs/backup-create)!
:::


After reading the warning above, select and delete all the files in that folder so that it is empty (leaving only the DB3 folder):

## Copy files the old files

Select and copy all the files in the old folder you found in the first step above, then paste them into where you just deleted all the files.

When you have done that, the folder will have similar to this:
