You can filter your updates according to these categories by clicking the arrow next to All and selecting a filter.
File updates are listed in chronological order, by user, with the most recent additions appearing at the top of the list. To prevent clutter, each action appears on its own line.
For more information about a file or folder, or to take action, you can click the name of the item. From the updates view, you can also click on the name of the folder where the item lives or the folder above that.
Note: The Updates Feed is meant to give you a high level overview of recent actions in your Box account. If you are an admin, you can find more comprehensive logs in the Reports Tab of the Admin Console.
