With Files On-Demand, all OneDrive and SharePoint files are visible in File Explorer or Finder but only take up space once they are opened. This saves a lot of storage on the device.
Status icons
Cloud: online only, uses no space. Opening requires internet.
Green check (white): was opened and is available locally.
Green check (solid green): always on the device, available offline too.
Free up space
In File Explorer (Windows) or Finder (Mac), right-click a file or folder in OneDrive.
Windows: choose Free up space. Mac: choose Remove Download.
The files remain visible and are downloaded again the next time they are opened.
Make available offline
Right-click › Always keep on this device, e.g. before a trip.
Turn on the feature (Windows)
Click the OneDrive cloud in the taskbar › gear › Settings › Sync and back up › Advanced settings › under Files On-Demand, choose Free up disk space and download files as you use them. This is usually already set on company devices.
Tip: If storage stays full, look for large files outside OneDrive, e.g. in the Downloads folder.
