You're welcome! That's what we do here.
Well, my guess is from doing home and business networking since 1980, is that you spent many many hours (probably 100+) getting your previous 2-PC folder/drive P2P sharing setup working.
If you didn't get it working yourself, and you brought some Tekky friend(s) in to help, they probably spent quite a few days at your place drinking your beer and eating your pizza to get that task accomplished.
I usually charge several hundred dollars to do what you have had previously setup.
My pricing also included wifi setup and printer sharing over the LAN as well.
You didn't mention what your previous windows versions were on those 2 PCs; but from XP-Vista era machines, that was quite a job for you.
If they were modern PCs; Win7 or W8x machines, and you didn't use Homegroups, that's like pulling out your own abcessed tooth with a pair of pliers and no local. I've done it, and it's rather painful.
Did you ever see the movie Castaway?? Like I said, from W7 on, Homegroups made things easier, and no more having to have Tekky friends shack up at your place for weeks at a time!
But, hey, it's your LAN, use it the way you want to! (a spin on the JG Wentworth TV ad; "it's your Money; use it when you want to!").
Cheers!
