To answer your question: The Handy Safe Desktop Professional database file is typically stored on your old computer's hard drive. When you connect the old hard drive to your new PC via a USB cable, you should be able to locate the database file in the default installation directory of Handy Safe, which is usually in the "Documents" or "Program Files" folder under a subdirectory named "Handy Safe" or "Epocware" (the developer). If you customized the location during installation, it may be in another folder. Look for files with .db or .hsk extensions. Once located, you can copy these files to the corresponding directory in your new PC's Handy Safe installation to recover your data.
