Word of warning: DON'T USE IT!! It can really screw up applications. In the case of N1MM+ that has a file in the Documents folder on your C: drive it will automatically back that up unless you are very careful. I've gotten myself in a real bind now with N1MM+ and maybe other apps but so far no problems with others yet....And it seems you can't reverse it once OneDrive has associated files with it. It's a real mess and Microsoft are real crooks to set something like that up as it also fills to free capacity limit quickly and then of course you have to pay them more $$$ to have more backup space.
I've reached the conclusion that both Apple and Microsoft are crocks! I wish I knew enough about Linux as I'd move my shack to that if possible.
73 to you both.
