You can filter your Videos & Files page by Title, User Name, or Group in the search bar at the top of your library.
On the left side panel, you can choose to filter by file type and by artifacts that were uploaded by you or shared with you but clicking on what you want to see.
You are also able to filter your Videos & Files by Tag. To do so, scroll down to the bottom of the page and filter by Tag in the left toolbar. In order for the filter by tag to work, your video or file must be tagged by you.
