Parse directory, collect all file entries.
For large PAK files (> 4 GB), mmap() (or CreateFileMapping on Windows) avoids loading the whole file into RAM. Use MAP_PRIVATE to safely read chunks. rechunk000pak better
: It increases the game's footprint from approximately 24GB of compressed assets to 41GB of uncompressed ones. Parse directory, collect all file entries
Conclusion: “Better” rechunking is than naive Python, with 29% better compression and alignment benefits for game streaming. rechunk000pak better
