Syntax

struct FPakEntry

Remarks

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.

Variables

	Name	Description
TArray< FPakCom...	CompressionBlocks	Array of compression blocks that describe how to decompress this pak entry.
uint32	CompressionBlockSize	Size of a compressed block in the file.
uint32	CompressionMethodIndex	Index into the compression methods in this pakfile.
uint8	Flags	Pak entry flags.
uint8[20]	Hash	File SHA1 value.
int64	Offset	Offset into pak file where the file is stored.
int64	Size	Serialized file size.
int64	UncompressedSize	Uncompressed file size.
bool	Verified	Flag is set to true when FileHeader has been checked against PakHeader. It is not serialized.

Constructors

	Name	Description
	FPakEntry()	Constructor.
