I'm gonna ask a very noob question so take it easy.
Is NMV recommended for modding? More specifically creating a new mod? 'Cuz I read somewhere that the previous editor, NFV, used to eat up mods.
KArthur90, take it from an old modder, it's definitely recommended for modding. Whenever I've used it it's worked fantastic, and it's nothing like the old Jan's File Viewer (which was great for its time, but just a bit buggy You'll find though that often you will still spend a lot of your time editing directly from the .dat files; this program is best used in combination with the old methods. Even if you don't wont to use it as an editor, simply use it to check your code before you open up Notrium, and to check that everything will do exactly what you intended it to. It's absolutely invaluable for that, and makes things so much easier.
I know the program copies back-up files automatically, but I would always recommend making your own periodic backups just in case. That isn't saying I don't trust the program, I simply do that all the time, even when editing the files directly. You don't ever want to risk messing up your whole mod because of one untraceable careless entry.
