Filetype:File Database

This page is a work in progress.

As a result, the layout and/or content herein may be subject to change.

The File Database filetype or map is a binary file format used by LittleBigPlanet games to store a list of assets and their metadata, and is used to load all of the files into the game. Common map files include the blurayguids.map which is the base map file, and brg_patch.map which is the patch map file.

Structure

The file consists of a header followed by a sequential list of file entries.

Header

The header is 8 bytes long and contains two 32-bit unsigned integers in big-endian format.

Offset	Length	Type	Description
0	4	u32	Revision: The version of the file format. The high 16 bits (>> 0x10) determine the variant. If the value is >= 0x148, it is an LBP3 map.
4	4	u32	Count: The number of entries in the file.

Entries

Each entry represents a file or asset. The structure of the entry depends on the revision of the file.

Path Length

The length of the file path string.

Type	Game	Length
u16	LBP3	2 bytes
u32	LBP1/2	4 bytes

Path

A UTF-8 encoded string representing the file path. The length is defined by the preceding path_len field.

Timestamp

The Unix timestamp of the file.

Type	Game	Length
u16	LBP3	4 bytes
u32	LBP1/2	8 bytes

File Size

A 32-bit unsigned integer representing the size of the file in bytes.

SHA1

A 20-byte array containing the SHA-1 hash of the file content.

GUID

A 32-bit unsigned integer representing the Global Unique Identifier for the asset.

Summary of Entry Layout

Field	Type (LBP3)	Type (LBP1/2)	Length
path_len	u16	u32	2/4 bytes
path	char[]		path_len bytes
timestamp	u32	s64	4/8 bytes
file_size	u32		4 bytes
sha1	u8[20]		20 bytes
guid	u32		4 bytes
