What specific steps must be taken in OneDrive to ensure that large video files are accessible offline on a mobile device without consuming excessive storage space?

To ensure large video files in OneDrive are accessible offline on a mobile device without consuming excessive storage, utilize OneDrive's Files On-Demand feature and selectively download files for offline access. First, enable Files On-Demand within the OneDrive settings on your mobile device. Files On-Demand allows you to see all your files in OneDrive without downloading them and taking up storage space. Files are only downloaded when you open them. Once Files On-Demand is enabled, browse to the specific video files you need for offline access. Instead of simply opening the video (which would download it), locate the 'Keep on this device' option (often found by tapping the three dots next to the file name). Selecting this option will download the video file to your device, making it available offline. Only choose 'Keep on this device' for the specific video files that you absolutely need offline. All other files will remain in the cloud and only be downloaded when accessed. This targeted approach prevents the entire OneDrive library, especially large video files, from consuming all available storage on your mobile device. Periodically review the files marked as 'Kept on this device' and remove the offline status from those no longer needed to free up space. Also, verify that your OneDrive app has the latest updates, as newer versions often include improvements to Files On-Demand functionality and storage management.
