Because this is "part 2," you cannot open or extract it on its own. You must have all pieces of the set to successfully access the contents. 1. Gather All Parts
Based on the filename , you are likely dealing with a multi-part archive for Illborne , a Japanese RPG (often associated with the "Wolf RPG Editor" engine) that has received an English fan translation.
This usually means one of the parts (often the one you just downloaded) is incomplete or corrupted. Try re-downloading that specific part.
