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.
