Drag-and-drop is not required to use the mod manager. Just put the .override (or DAzip) in the appropriate storage folder you made, set the file paths, and it will show up in the DAO-ModManager interface.... changing the extension will render it useless. If you aren't going to use the mod manager at all then you can't use configurable .overrides at all, since DAO-ModManager is required for configuration part. (The format is proprietary and unique to the utility.) DAzips can be installed with the native Bioware daupdater utility, of course, and manual overrides can be installed by copying the files to the correct folder ([user]\Documents\BioWare\Dragon Age\packages\core\override). Thanks so much, I'm about to give it a try.
