By default, Arma Reforger downloads mods to your Documents folder on your C: drive, following this path: Documents\My Games\ArmaReforger\addons


I have a small C drive, only 120 gigs, and most of it is taken up by important programs. I sought a fix, but found that just like every other thing on the internet the only people explaining how to do something leave out key details that one can only know by having the 'tism, so I wrote this short guide to help you out.


1. Create a folder called addons on your perferred drive. for this guide, I've done so on the D drive.
2. Right Click Arma Reforger
3. Properties
4. Under "Launch Options" add the following

-addonDownloadDir D:\addons -addonsDir D:\addons

Thats literally it. If you already have those files on your C: drive, all you have to do to avoid redownloading is copy the files to the new addon folder you made in step one, then clear that folder out on your C: drive
