Archive format used many Maxis developed games, includingr The Sims 2 and SimCity 4.

Contents

Format

Most Sims 2 Data is as you probably know stored in various types of archive files that all have the same internal format such as package, cache, etc. This format is proprietary to Maxis and has been used in the SimCity 4, and The Sims Online as well as this one.

Entries may be compressed with RefPack compression depending on their entry data.

Overview

This is the general structure of DatabasePackedFile packages:

Header (96 bytes) 

File 1
File 2
...
File n
Index Entry 1 (20 bytes)
Index Entry 2
...
Index Entry n

Header first, individual files following with no filenames and a small file header area at the beginning of each followed by an index of all the files in the archive. Note that files may appear after the index table in files that are updated.

  • 1.1 seen in The Sims 2
  • 2.0 seen in SPORE

Index offset 2.0 u32 Offset to Index table in DBPF 2.0.
unknown 2.0 u32
reserved char[24]

Index Table

There are 2 known formats of indexes in the game. The format version is found in the file header.

DBPF 1.x, Index table 7.0

(20 bytes, some DBPF 1.1 entries use this format)

DWORD
Type ID (see InternalFormats)
DWORD
Group ID
DWORD
Instance ID
DWORD
Location of the file in the archive
DOWRD
Size of the file

DBPF 1.x, Index table 7.1

(24 bytes)

DWORD
Type ID (see InternalFormats)
DWORD
Group ID
DWORD
Instance ID
DWORD
Second Instance ID
DWORD
Location of the file in the archive
DOWRD
Size of the file

Hole Table

DBPF 1.x

A Hole record contains the location and size of all holes in a DBPF file.

repeating
DWORD
Hole Location
DWORD
Hole size

Holes are created when the game deletes something from a DBPF. The holes themselves are simply junk data of the appropriate length to fill the hole.

File

Bulk of DBPF packages. Each file is either uncompressed or compressed. To check if a file is compressed you first need to read the DIR resource, if it exists. (See the corresponding entry for a description). If no DIR entry exists, then no files within the package are compressed.

Compression

When reading a DBPF file, the first thing you should do is check to see if any chunks inside are compressed. This is done via the DIR resource.

For example code and a description of the mechanics, see DBPF Compression.

Directory Files

These are used for compression lists. See E86B1EEF

Header

Only if the file is compressed

DWORD
Compressed Size of file
WORD
Compression ID (0x10FB) QFS Compression. (See packages for compression information)
3 bytes
Uncompressed Size of file

Body

Raw data of the files. See InternalFormats for a list.

Pseudocode

To read files inside a .package file you need to perform the following steps, in order

  • Read the DBPF header
  • Read the Index tables
  • Check for a DIR record
  • Check for the file you want to extract
  • Is this file compressed? If so, uncompress it
  • Read the file data and process accordingly

For an example PHP class for reading DBPF files, see DBPF/Source Code
