Need help. PS4 Game File transfer to PC.

[TheGmodNugget]

Here's the gist. I put my PS4 copy of RDR2 onto a 256GB flash drive. Formatted it to act as an external drive. Now I'm having trouble placing it onto my PC because Windows doesn't recognize the format. The format is just known as PS4 when placed into my console. The question is, is there either, A: is there a way to access it on my PC, or B: is there a program that can read PS4 formatted drives and can extract the files on the drive.
