PackIndex Asset

The packindex asset exists only in Black Ops 1 and World at War. It most likely holds pack file indexes..

struct PackIndexEntry	// 0xC
{
	unsigned int hash;
	unsigned int offset;
	unsigned int size;
};

struct PackIndexHeader		// 0x14
{
	unsigned int magic; // "PAK0"
	unsigned int timestamp;
	unsigned int count;
	unsigned int alignment;
	unsigned int data_start;
};

struct PackIndex		// 0x1C
{
	const char *name;
#ifdef PC
	PackIndexHeader header;
	PackIndexEntry *entries;	// count = header.count
#endif
};
