Essentially it keeps a copy of the mod in its own directory. Also, if you EVER have to reinstall Skyrim, your NMM mods do not delete, just after installing you will have to deinstall all the checks in NMM n reload them in. To OP: no you do not need to have Steam up n running to use NMM. :DĪlso, 242 mods do you have also texture mods on top of that?! That, to me, would take some serious work to handle. Therefore, I update my Nexus ones after one playthrough, meaning I start a new chr and a new save and never load the previous one. Also, I wonder if prolonged use of the auto-update essentially nukes the save. I don't have near as many mods and use Nexus exclusively due to workshop's 'auto-update'. Nice choice in games there Kenneth ) Myst, et.al Neways, yes, Boss does become problematic after a certain point. I order the mods using only NMM as I found that programs like BOSS just made an unmanageable mess that resulted in CTDs. I am currently using: 247 downloaded mods which results in 242 ESM/ESP files which includes Skyrim and DLCs. NMM displays a flag for new versions of a mod, so I can go to the Nexus and check out the changes. I have complete control over when mods are installed. I shifted to the Nexus and use the Nexus Mod Manager (NMM), exclusively. Originally posted by kenneth.underwood:In the beginning I used the Workshop for mods, but I disliked the lack of control over mod updates.
