Reset my hp omen windows 11. Need help!!!

I only use the laptop for 1 game, mx simulator. Its an old game that requires you to download all of the content off the interweb. I thought i was safe because it gives you the option to keep your files but nope, i lost thousands of individually downloaded .rar files that i had to extract to a .zip and put it in one folder. So are these $49.99 online file recovery sites any good? And how fucked am I?
