Hello, I'm at the 2.K. Clutter and Miscellaneous portion of the step guide, I'm currently trying to install the Skyrim Redesigned mod, but it's telling me to "rearchive" the Skyrim Redesigned folder. I don't know what that means, is there an exact wording for re-archiving or some sort of simple instruction on how to do this? Thanks, Archcaduceus
