Backup and Restore Data

Before reinstalling the PDD software, please back up the PDD data file. All of your entered pets, recipes, and user-defined foods/supplements can be found in one file.

To copy the data file to a thumb drive, follow the instructions below:

 1) In Windows Explorer, type %appdata% (with the percent signs) in the menu bar and press Enter. You will go to the “application data” folder.
2) Scroll to the bottom and look for a file called “pdd03.sdf”. When you find this file, just copy it. This file contains all your data.
3) Uninstall the PDD software program.
4) Download and install PDD from the link provided in your download email.
5) After reinstalling, check to see if your data still exists. It should. If not, then go to Step 6.
6) In Windows Explorer, type %appdata% (with the percent signs) in the menu bar and press Enter. You will go to the “application data” folder. Copy the old data file (pdd03.sdf) to this directory and choose to overwrite the existing data file that was created when you installed PDD. You should now have all of the data for your pets and recipes.

Reapply the license key (via the link in your license key email) if needed.

That’s it…

There is only one file which holds all of your pet and recipe data. Follow the instructions below to make a copy of this file. You should store this file on a thumb drive or some other storage media apart from your computer.

In Windows Explorer, type %appdata% (with the percent signs) in the menu bar and press Enter. You will go to the “application data” folder. Scroll to the bottom and look for a file called “pdd03.sdf”. When you find this file, just copy it. This file contains all your data.

First, make sure the PDD on the old computer is up to date with the latest version. The top of your screen should say “Pet Diet Designer (v.88.3).”

You will need your data file (which holds all of your recipes) and your original license key, which was emailed to you when you purchased PDD.

In Windows Explorer, type %appdata% (with the percent signs) in the menu bar and press Enter. You will go to the “application data” folder. Scroll to the bottom and look for a file called “pdd03.sdf”. When you find this file, just copy it. This file contains all your data.

On your new computer, download and install PDD using the link in the download email you received.

After successfully installing PDD, you will have a new copy with only sample recipes. To get your own recipes, close PDD for Windows.

In Windows Explorer, type %appdata% (with the percent signs) in the menu bar and press Enter. You will go to the “application data” folder.

You should now have all of the data for your pets and recipes.

Reapply the license key.

In Windows Explorer, type %appdata% (with the percent signs) in the menu bar and press Enter. You will go to the “application data” folder. Copy the old data file (pdd03.sdf) to this directory and choose to overwrite the existing data file that was created when you installed PDD.

If you wish to keep the recipes that you have created, then you have to copy your data file to the new computer. There is only one file to copy. In Windows Explorer, type %appdata% (with the percent signs) in the menu bar and press Enter. You will go to the “application data” folder. Scroll to the bottom and look for a file called “pdd03.sdf”. If you find this file, then copy it to a thumb drive. This file contains all your data.

On the computer that you want to copy the data file to, also type %appdata% (with the percent signs) in the menu bar and press enter. You will go to the “application data” folder of the new computer. Now, copy the “pdd03.sdf” file from the first computer to the new computer. This will overwrite the data file with your saved recipes.
