Hello everyone, I'm pulling a dumb move here but how do I "drag and drop" the mediafire download links of mods. Where should I save them in my New Vegas directory?

Just drop them in the "Data" folder - unless it's something like an ENB or FNVE, then put it in the base Fallout New Vegas folder.
Hope this helps!

Hello!

With time you're gonna get used to the "Data" folders and paths, like the textures/meshes, NVSE, custom mod paths and so on, but yeah "drop the files in the data folder" is pretty much it with almost every mod.

After that, be sure to tick every mod on the Mod manager, and the "Archive Invalidation"

Be sure to read every mod description before installing, also you should learn how to install a fomod package and stuff
