How to Use OneDrive Files On-Demand to Sync Your Files
OneDrive is Microsoft’s cloud storage solution that makes storing, accessing, and sharing files easy across multiple devices. One of the most useful features it offers is Files On-Demand, a smart syncing technology that lets you access all your files from File Explorer without having to download everything to your device. This feature helps save disk space, improves performance, and allows you to choose which files are available offline.
In this guide, you’ll learn exactly how Files On-Demand works, how to enable it, how to manage your files efficiently, and how to troubleshoot common syncing issues. Whether you use Windows 10, Windows 11, or OneDrive for Business, this guide covers everything you need to know.
What Is OneDrive Files On-Demand?
Before learning how to sync with Files On-Demand, it’s important to understand how the feature works. Introduced in Windows 10 and improved in later updates, Files On-Demand gives you a full view of your cloud-stored files directly in File Explorer without downloading them to your computer.
Key Benefits
-
Saves local storage space
-
Gives instant access to cloud files
-
Syncs files only when you need them
-
Allows selective offline access
-
Works with both personal and business accounts
Files On-Demand uses simple icons to make file status easy to understand.
File Status Icons
-
Cloud icon: File is online-only and not stored locally.
-
Green checkmark outline: File is locally cached temporarily but can revert to cloud-only.
-
Solid green checkmark: File is always available offline.
Understanding these icons makes the OneDrive experience more intuitive.
How To Enable OneDrive Files On-Demand
Enabling Files On-Demand is simple. Most new Windows versions have it turned on by default, but it’s always good to check.
Steps to Turn On Files On-Demand
-
Click the OneDrive icon in the taskbar system tray.
-
Select Settings.
-
Go to the Sync and backup or Settings tab (depending on your version).
-
Scroll to find Files On-Demand.
-
Check the option Save space and download files as you use them.
Once enabled, OneDrive will immediately begin showing placeholder files without downloading everything.
How To Choose Which Files Sync to Your Device
With Files On-Demand active, you can decide which folders or files should stay online-only and which ones should be available offline.
Making a File Online-Only
-
Right-click the file or folder.
-
Select Free up space.
-
OneDrive removes the local copy but keeps the file accessible in the cloud.
Making a File Always Available Offline
-
Right-click a file or folder.
-
Choose Always keep on this device.
-
OneDrive downloads the file and keeps it permanently stored on your computer.
Using Selective Sync
If you want to exclude entire folders from appearing on your PC:
-
Right-click the OneDrive icon.
-
Go to Settings → Account → Choose folders.
-
Uncheck any folders you do not want to appear in File Explorer.
Selective Sync is useful if you store large archives on OneDrive but rarely use them.
How Files On-Demand Works With Storage Sense
Windows 10 and Windows 11 include a feature called Storage Sense, which automatically frees space by removing temporary files. It can also convert unused OneDrive files to online-only.
If you want Windows to help manage OneDrive storage:
-
Open Settings.
-
Go to System → Storage.
-
Enable Storage Sense.
-
Adjust how often it should remove unused cloud files.
This automation ensures your hard drive stays clean and optimized.
How To Sync Files Across All Devices
Files On-Demand works seamlessly with other OneDrive-enabled devices, including Windows PCs, macOS, Android, and iOS.
