I have a question about installing this mod, specifically this step:
I suspect I just don't understand something very basic about archiving files. How does one rename it to Skyrim Redesigned-8954-1-0 but end up with a file without the -1-0 in it?
There are a couple of steps described in the wiki that need to be completed.
You need to download not only the original file but also the FOMOD file and temporarily extract BOTH of them.
Then move or copy the FOMOD folder into the folder structure of the Skyrim Redesigned mod. This the part where it mentions 34 individual folders instead of the original 33 from Skyrim Redesigned.
What you should have now is a folder structure with Skyrim Redesigned as the top level and 34 folders underneath it including the fomod folder.
Using whichever archiving tool you have, 7zip is a very good one to have, compress this folder structure and name accordingly. The wiki says to name that way because that naming convention allows MO to see the Nexus ID:
and the version number:
The actual process of naming the archive is handled by you using whichever tool you have.
