Best Compression Methods for 'Specific' Games. Q&A

[Fak Eid]

Hey, I'm new and don't even know if this question is relevant here. But I need help:

1. How to identify language files from a game. Is there a tool for it? Like for some games like Spider-Man Remastered and GotG, I was not able to locate language files.

2. I'm currently using Ultra compression method of FreeArc (-mx -ld1600m), and using fazip.exe to decompress, but it takes around 1hr to extract Uncharted: Legacy of Thieves Collection. (99.2 GB compressed to 64.4GB). My FreeArc version is 0.67, however my fazip.exe version is 0.0.3 (and a decade old from 2013). Can someone provide me a link to the latest fazip.exe and fazip64.exe files.

3. Also, to decompress, what is the difference in time between fazip.exe and fazip64.exe.
