OneDrive has revolutionized cloud storage by providing seamless access to files across multiple devices. One of its standout features is Files On-Demand, a functionality designed to help users save space on their local devices while ensuring quick and easy access to all their files stored in OneDrive.
How Files On-Demand Works
With Files On-Demand, users can view all their stored files in File Explorer or Finder without needing to download them. The files appear like normal files but do not consume local storage unless opened or marked for offline use. This feature is particularly useful for users working with limited storage on their devices.
OneDrive categorizes files into three main states:
- Online-only files: These files appear in File Explorer but do not take up space on the device. They download only when opened.
- Locally available files: When an online-only file is opened, it temporarily downloads onto the device, allowing access even without an internet connection.
- Always available files: These files are manually set to remain on the device and never revert to being online-only.

Benefits of Using Files On-Demand
OneDrive’s Files On-Demand feature offers several advantages, including:
- Storage optimization: Keep a full list of files without consuming local disk space.
- Access from anywhere: View and manage OneDrive files from any device.
- Faster syncing: Sync only the files in use rather than downloading everything.
- Security and reliability: Files remain in the cloud, reducing the risk of accidental loss due to device failure.
Enabling and Managing Files On-Demand
To activate Files On-Demand, follow these simple steps:
- Open OneDrive settings by clicking the cloud icon in the taskbar.
- Go to the Settings tab and locate the Files On-Demand option.
- Check the box that says Save space and download files as you use them.
- Click OK to apply the changes.
Users can adjust file availability by right-clicking a file or folder in OneDrive and selecting:
- Free up space to revert it to an online-only file.
- Always keep on this device to make it available offline.

Common Use Cases
Files On-Demand is beneficial for various users, such as:
- Students: Access and manage course materials without overloading their laptops.
- Professionals: Work on projects across multiple devices without worrying about storage limitations.
- Photographers and creatives: Preview and organize media files without downloading everything.
