DataBase Packed File

Are MySims way of packaging files, they are also refered to as DBPF and use the extension .package.

Files

MySims (PC) contains these package files and are found in MySims/SimsRevData

Format

DBPF have some different names for the files that are inside, in this documentation we will refer to them in the following way:

• Instance, hash - The name of the file. eg: ticketmachine
• Group - This is like a folder, for example the ticketmachine group contains both the files for the model and material of the ticketmachine.
• Type - This is the same as a file type, eg: windowsmodel, material or xml

Its important to note that some of these values have not been unhashed and thus are refered to by their instance id, instead of an actual name.
