Assume you backed up your data, your program became corrupted, and you uninstalled and reinstalled it, or you are installing it on another computer.

In Windows Explorer, type %appdata% (with the percent signs) in the address bar and press Enter. This takes you to the “application data” folder. Copy the old data file (pdd03.sdf) to this directory, and choose to overwrite the existing data file created when you installed PDD. You should now have all your pet and recipe data.
