Where are failed install files located?

[Pyromaniac1111]

I've tried to install Tale of Two Wastelands with NMM which obviously didn't work for me, and now, because of the size of it, it's taken up quite a bit of space on my computer (at least, I'm assuming it also took up space, as it took up a lot of space when I did it with Mod Manager and cancelled it). But, the space it took up is still taken up, so I'd like to know where the files would be located for the failed install.

One we don't support Tale of Two Wastelands here, so you probably shouldn't even have tried to install it with NMM.

 

Second, faik if NMM attempts to install a mod and doesn't finish it it doesn't leave partial files behind. To check, open up a manually downloaded version of the mod and look at it's folder structure and what unique items it contains, then locate the same locations in your Data folders and see if the unique files are still there, delete any related to the mod you're trying to remove.
