Need help with unzipping a .gz file

I recently got this unity package off one drive and when I unzipped the file it gave me a gz file, after my first try at unzipping the gz file it turned into a mess of files with random numbers and letters names, in each folder there are 2 files one named just "file" or "meta.file" Im trying to import these files into unity for vrchat but it doesn't work i have no idea what I'm doing.

Im on windows 11 and I'm using unity 2022.3.23f1
