files.db structure
Warning : This structure is still uncertain/not complete
files.db is organized in blocks of 1024 bytes, the first block is the header of the file, its structure is still unknown.
Each block contains 4 sub-blocks :
- Block header
- Filenames (9 entries)
- File informations (9 entries)
- Hashes block?
Note : Numbers are stored in little-endian.
Block header
0x10 bytes wide, structure is uncertain.
typedef struct { u32 id; u32 type; u32 nfiles; u32 unk1; } bhead;
id :
- 0xYY : Block identification ? generally 0x02
- 0xffffffff : ???
type
- 0x00 : The block will describe files and parent directories.
- 0x01 : ??? Ignore, changes structure of the current block.
nfiles :
One block describes up to 9 files, although it can be less, nfiles is the number of files described in the current block.
unk1 :
Padding ?
Filenames (9 entries)
9 entries of 72 bytes, describing filename and parent directory.
typedef struct { u32 idx; char filename[68]; } fname;
idx :
Describes parent directory of current file entry. (Cf. File informations block)
filename :
Filename of current file entry (68 bytes, null terminated).
File informations (9 entries)
9 entries of 0x10 bytes.
typedef struct { u32 idx; u16 type; u16 unk1; u32 size; u32 unk2; } finfo;
idx :
Used to retrieve parent directory for filenames block, each file entry has its own index, 0 is for root.
Example :
File/Dir | idx (fname) | idx (finfo) | Path |
---|---|---|---|
lol.png | 2 | 3 | /images/abcd/lol.png |
abcd/ | 1 | 2 | /images/abcd/ |
images/ | 0 | 1 | /images/ |
eboot.bin | 0 | 4 | /eboot.bin |
type :
- 0x01 = normal file
- 0x8000 = directory
- 0x4006 = unencrypted system file
- 0x06 = encrypted system file
unk1 :
???
size :
Size of the current file.
unk2 :
Padding ?

ListDirVita is a simple parser for files.db (Still WIP) [1]
