HowdyNyallMods

I'm having to rebuild my library, but I can't remember which mod I got these hairs from. I've downloaded several air mods (more hairstyles, random hairstyles, hairstyle day etc) but I cannot find them. Does anyone know? Sorry the photos are such poor quality, this computer does not allow game screenshotting. I hope this formats correctly.....we'll just ignore what's going on with Shale in the last pic, it's just to show the hair from the back.

I am new to modding, new to PC in general (mac user, had to google how to open my files. that is how dumb I am.) Based on my research, it's my understanding that manual mods (not dazip ones) go in the override folder. But when I open my game, they don't seem to be working. Is it more complex than this? Attached is a screenshot of my override folder. (I know the mod for Merril had other requirements- I believe I have placed everything there it needs?) Edit: Can't figure out how to screenshot it sorry. Edit 2: Took a photo! Old fashioned!
