Xbox storage files

Well ok,but on dev mode i also have emulators and i can download roms,but in a limited number,also i only download in microsoft edge,and it tells me the same things

That's because the emulator you run in Dev Mode might reserve enough room inside it's own special sandbox to store the downloaded roms.

But Microsoft specifically disabled the storage of downloadable files in the Edge Browser app. It's just not possible to do in this particular app.

If you are knowledgeable enough, you can write your own browser UWP, and sideload that to the console, and allow that app enough storage to allow downloading.

But with the built in Edge browser, you can't download anything anywhere.

Since you are just using the internal drive there is probably no more room on it for data files. Most of the space it reserved for games.

I dont have an external.drive

Hello Momo,

Thanks for keeping us updated. It would have been helpful to let us know you were in Developer mode from the get go, as what you are trying to do is not possible in retail mode.

Basically you want to put an external file that can not enter the console, I'm sorry but you can not download a file not recognized by the console. In addition to the system and saved games.
