A File Share is an online storage space for Halo 3, Halo: Reach and Halo 4 players. Every player gets their own File Share (one per Xbox Live gamertag) and may upload screenshots, films, film clips, map variants, and game variants.

On Halo 3, a default File Share can hold up to six custom content items; players who subscribe to Bungie Pro (at the cost of 750 Microsoft points per year) will have their File Shares expanded to hold twenty-four items. For a limited time, Bungie Pro was free for four months with the purchase of the Legendary map pack.

You are required to have an Xbox hard-drive to access your fileshare.

On Halo: Reach, a file share has no capacity limit on the number of files held there.

File Share items are also displayed on From, they can be organized into groups (called "File Sets"), tagged or downloaded to a computer.

As part of the final transition between Bungie and 343 industries, 343 gave free Bungie Pro to all Halo 3 players on March 29, 2012.

At Halo 4's launch the file share was unusable until a patch in early 2013.
