Another new plugin added to the Moodle plugins database is the Recent files Block which allows you to see recently uploaded or modified files and folders from all your courses you are enrolled in and pin them for easier access with this block.
Acc. to the plugin description:
The recent files block provides a moodle block which shows a configurable number of the most recently uploaded or modified files and folders in the courses the user is enrolled in with a startdate somewhere within 7 months from the current date, thereby filtering possibly stale courses. It also provides an option for the user to pin files and folders for later reference.
