Here is how you can do it: • Go to Files from the left-hand-side navigation bar, open All Folders (read: Data Rooms), and select the Folder (read: Data Room) you are interested in. • Then, click the Green 'Upload file' Button in the top right corner. Pick the video from your PC/laptop and drag it to the Upload Files Window. You can update the name of the file in that window as well. If the file is large, it may take a few minutes to upload it. We do not have a limit for the file size.  • Once uploaded, it will directly open that file's page. You can either copy and open the file in a new browser by clicking the chain icon in the top right corner or clicking the eye icon to preview it in Decile Hub.  Here is an Arcade Video tutorial with the answer: https://app.arcade.software/share/F9MhcA1fgLUv7EjyX5ir
