NMM - manually downloaded mods

[NeitherShady]

Hello,

 

first I want to say sorry for my bad english, I'm from germany.

 

And now my problem:

 

I always downloaded my mods manually, but now I want to switch to NMM, cuz I saw in some videos it's very good and now I install it and everything, the path of my mods is right but NMM don't reconize my mods, but when I download em with NMM then its fine, but my "old" mods can't be found.

 

Is there something I can do, or do I really need to download all my mods again with NMM?

 

Thanks for helping!
