All the things i seem to download from here are .rar files, which to my understanding are useless, why is this happening?

@stillhere
... All the files are now .rar files for some reason... For every mod I download down OpenIV run them?

@stillhere Thank you

And I mean to make them accessible... Not talking about WinRAR, Only made it WORSE for me... Also, Need help to get into rpf files

I get at least.... Some of these mods, but the more advanced ones I don't get, for instance, I need to get into a .rpf file to get a mod inside...

Can anyone help?
