The title says it all. How can I open .fpk files on vista? PakBuild won't work for me.

Yes it does. Open PakBuild, then select unpak and direct it to the .fpk file. You can't just open it by clicking it.

Oh, thanks.

Not exactly the same question, but related so why waste it on a new thread?

Anyway, has anybody else had an issue with PakBuild where it will fail to unpak all of the files? I have had this happen to me on quite a few occasions/mods where it is an unfinished unpacking. Files will be missing here and there and I was wondering if this was related to Vista (because that is what I use) or maybe my version of PakBuild (if a new one had been made). Anybody know?

What do you mean some files are missing? Also, you could also try other fpk unpaking utilities.
