Have alotof large mods find NMM takes forever to launch? Heres a way to reduce that down to few seconds. The problems caused by having alotof large mod archives in the NMM mods folder which it likes to scan before starting up, but its unnecessary cause it only needs to know the file names match. A way around it is to trick it at the scanning stage by making it look at dummy archives instead of the real mods. You can still install the real mods once the programs launched, you just need to swap out the dummy file with the real one before double clicking it to install. Ive worked out a streamlined way of doing this where you only need to change two folder names to work it.

5) optional - add a word doc in each folder titled "Dummy xxx" with xxx for the mod name so if you install the dummy file by accident youll see that in the data folder and know what to do

You can still uninstall mods with the dummy folder loaded but allways need to be careful after downloading new mods: they need to copied to the real mod folder and given a dummy to sit in the dummy folder: the two folders allways need to be identical but this can still be done with NMM open, its just inconvenient and means you cant install previously downloaded mods until new ones have been duplicated like the rest.

Sixth. in the NMM archive folder, highlight the first archive, click again and copy the archive.

Alternatively if you only have a few really large mods but alotof small ones, can just replace those few instead of doing the whole folder swap

How to Speed up the launch time of NMM if it's behaving laggy (I don't think this is translatable to OBMM, FOMM or WryeBash:


If it's taking the program more than 10 or 20 seconds to load, the cause is likely that you have a lot of large mods in the NMM archive folder. I stumbled on a way to speed it up. You can replace the larger archives with empty clones. So, on startup, it sees the clone and assumes that's the original. The reason for this is that it normally goes though a process of loading archive files into temporary memory (I'm not of sure the correct, technical, explanation) based on the sum of their size on disk, for example I've had over 10GB in archives and it's taken up to 2 minutes to start; considering NMM is also a download manager, it can take however long before the downloading of mods can begin—this can be pretty frustrating.


Note: This is best done to large mods you've already installed, or ones you don't plan to install straight away. The empty clones cannot be used to uninstall the mods and need to be replaced again with the original files to uninstall their contents from the Data folder. This is also a good trick to use if you're cloning the game folder and archives are stored there.

First, make sure NMM is closed.

Second, make a note of all the archives larger than say 200MB you're comfortable removing.

Third, make a desktop folder, name it something "NMM Clone archives."

Fourth, create two subfolders, one called "Clones", the other "Originals."

Fifth, in the Clones folder create as many subfolders as archives that will need replacing.

Sixth. in the NMM archive folder, highlight the first archive, click again and copy the archive.

Seventh. in the Clones folder highlight and click a subfolder and paste the copied archive there (do it to ensure exact spelling and spacing).

Eighth, deselect and right click it, then archive it using the same format the original has (zip, rar, 7z, etc.).

Ninth, when all the large archives are cloned like this, you can delete the clone folders they were made from.

Tenth, in the NMM archive folder highlight all the originals that were cloned (hold down Ctrl to select multiple files/folders at once) and cut/paste/move them to the "NMM Clone archives/Originals" folder.

Eleventh, move the empty clones to the NMM archive folder.

Twelfth, start up NMM again and check to confirm it's working. If so you will notice it loaded significantly faster. This method is specific to each game's archive list .
