Never Seen this before

I used Emule and d.l final fantasy 8 which is 4 cds. When i use win rar i get 5 files which unknown to me. They are :
DISC1.PAK-401,616KB
DISK1-1KB
FIELD.FL-120KB
FIELD.FI-32KB
FIELD.FS-287,230KB
I don’t know how to burn this so the game would actually work b.c usually i get files with a .cue and .bin. I believe that perhaps this is the game for Playstation not PC and that is why theses files seem different. However the title said that its for PC so im lost…
Please help
Thankx
