Sometimes when I try to download a new mod it'll download as .rar file not a .pnt or .pkz folder and it wont work. Is there a way to fix this or what am I doing wrong? Sorry if this is a dumb question Im brand new to pc gaming.
.rar ist a type of compression format, just like zip. See it as a well packed suitcase saving space, but you need to open it to access its contents.
So open the .rar with a software like 7zip or WinRAR and move the contents where they should be.
