I’m trying to drag and drop files that I downloaded for fallout new vegas I really need help.
Are you positive that they are Xbox 360 files? I’ve seen many people download files for the PC version of New Vegas and try to add them with Horizon. They’re not compatible and it won’t work.
If you know you have valid 360 files make sure you unzip them first if they’re in .zip or .rar containers. Or if you have a hard drive connected and are running Horizon as administrator you can’t drag & drop, instead use the inject option to get the files on your device.
