What about *.vpk from Half-Life Alyx? LZ4 algo?

Seems to have lz4 compression but for some reason xtool is not able to process the streams:

Please may someone upload a sample, such as
game/hlvr/maps/a1_intro_world/a1_intro_world_skybox.vpk?

Thanks!

I am using Diskspan with xtool+srep+lzam(1 and 2) and i am getting this error

Code:

WARNING: can't open file "E:\Kerbal Space Program 2\KSP2_x64_Data\StreamingAssets\aa\StandaloneWindows64\parts-base_assets_generator_0v_thermoelectric_radioisotope_icon.png_62877585fabce190dba4ae03f3ade21f.b  9.4%

i was thinking of using lolz but it takes too long. i tried the xtool unity plugin but that didnt seem to help.

Just the small ones. All of the big files are not compressed it seems.

Code:

Compressed 1,762 files, 32,373,757,878 => 37,763,790,489 bytes. Ratio 116.65%
Compression time: cpu 14.59 sec/real 877.50 sec = 2%. Speed 36.89 mB/s
All OK

Star Ocean: The Divine Force

Code:

Could someone send me a small sample, like "chunk_0\prop.cpk", from "Star Ocean The Divine Force"?

Would be appreciated
