This looks like a modified UE4 pak-file, but with LZ4 compression. Luigi's script doesn't work, unfortunately. Luckily, the TOC seems pretty easy - it's in the end of the .pak, after each name there is a pointer inside the pak. Each chunk has 21 bytes header with compressed/decompressed size. In TOC there is a list of chunks, they also look like starting/ending hex offset or size.

The largest .pak is 35 GB, btw.

My BMS skills are too mediocre to write a parser/extractor, so I hope for help of this community.

Modified archive with version 4, had to support it by checking the name of the archive.

Thank you! Strangely, it doesn't work on some files. Here is the smallest of them.

Script updated, now I use "-UWP" instead of "GearGame" for recognizing this format.
