I’m assuming it’s just one of the many glitches 343i is hopefully trying to fix w/ the “introduction” of File Share, but I figured I’d mention that it does not actually clear the download history when prompted. At the moment, it just resets/refreshes the page.
“Xbox Downloads” is a list of files that have already been downloaded to your Xbox 360.
“Clear Download Queue” clears your pending downloads.
So when you click it, all of your pending downloaded are cancelled.

I understand that “queue” is similar to “pending”, however, this is the message that appears after clicking “Clear Download Queue”:
Clear Download Queue? This will remove all Pending and Complete Downloads.
The message includes the word complete. To me, a complete download implies that it has been copied to the Xbox 360. The prompt needs to be edited, unless my assumption is incorrect.
The prompt is in error, and it will be corrected soon.

It seems to show files that you’ve loaded in the in-game browser but not actually downloaded. I’ve got a few bad screenshots in my history that the game loaded even though I didn’t download, a few are of Kat… How embarassing 
Just thought I would bump since it is still broken.
