Detailed Description

Struct holding info about a single file stored in pak file.

CHANGE THIS FILE RARELY AND WITH GREAT CARE. MODIFICATIONS WILL RESULT IN EVERY PAK ENTRY IN AN EXISTING INSTALL HAVING TO TO BE PATCHED.

On Fortnite that would be 15GB of data (250k pak entries * 64kb patch block) just to add/change/remove a field.

Member Data Documentation

CompressionBlocks

TArray<FPakCompressedBlock> FPakEntry::CompressionBlocks

Array of compression blocks that describe how to decompress this pak entry.

CompressionBlockSize

uint32 FPakEntry::CompressionBlockSize

Size of a compressed block in the file.

CompressionMethodIndex

uint32 FPakEntry::CompressionMethodIndex

Index into the compression methods in this pakfile.

Flag_Deleted

const uint8 FPakEntry::Flag_Deleted = 0x02

static

Flag_Encrypted

const uint8 FPakEntry::Flag_Encrypted = 0x01

static

Flag_None

const uint8 FPakEntry::Flag_None = 0x00

static

Flags

uint8 FPakEntry::Flags

Pak entry flags.

Hash

uint8 FPakEntry::Hash[20]

File SHA1 value.

Offset

int64 FPakEntry::Offset

Offset into pak file where the file is stored.

Size

int64 FPakEntry::Size
