f you have copied the entire .Piktures folder, your photos are safe. The d1.dat has the encrypted information about your account to provide you back access. But your photos are inside subfolders like 02, 15, 04 etc... th!s is where your photos are. If you have those folders, you are good, you just need to reinstall Piktures and relaunch the Secure Drive. It will detect your previous installation and you need to enter your email address and previous PIN code.
