PSdZData Lite contains only the metadata required for reading, editing, and writing coding files (FDL Coding). It is much smaller in size (usually under 2GB). PSdZData Full contains all the actual firmware files needed to flash or update software on your car's ECUs and is massive in size (often over 100GB).
