Manage OneDrive file syncing
Configures how OneDrive syncs files between this PC and the cloud, including which folders sync, Files On-Demand behavior, and bandwidth limits for uploads and downloads.
How to open OneDrive Sync Settings
- Click the OneDrive cloud icon in the system tray
- Open Help & Settings → Settings
- Go to the Account tab to choose folders to sync
- Go to the Settings tab to enable Files On-Demand and set bandwidth limits
What you should know
- Choose which OneDrive folders sync to this specific device
- Enable Files On-Demand to save local disk space
- Set upload and download bandwidth limits
- Pause syncing temporarily or view sync activity and errors
Why it matters
OneDrive sync settings determine both how much local storage your cloud files consume and how reliably your documents stay backed up and available across devices. Files On-Demand in particular can free up significant disk space on smaller SSDs by keeping files cloud-only until opened, but misconfiguring folder selection can lead to unexpectedly large downloads or missing files when offline. For anyone relying on OneDrive as a de facto backup, understanding these settings prevents sync conflicts, storage surprises, and confusion about which files are actually available offline.
Best practices
- Enable Files On-Demand on devices with limited local storage
- Selectively sync only the folders you actually need on a given device
- Set bandwidth limits if OneDrive syncing slows down your internet during work hours
- Check the OneDrive activity center periodically for sync errors or conflicts
Common problems and fixes
- Files show a cloud-only icon and won't open offline
- Right-click the file or folder and choose 'Always keep on this device' before going offline.
- OneDrive is using too much disk space
- Enable Files On-Demand so files stay in the cloud until you open them.
- Sync is stuck or shows an error icon
- Open the OneDrive activity center from the taskbar to view specific error details and resolve conflicts.
Tips and tricks
- Use 'Free up space' in File Explorer to convert local files back to cloud-only without deleting them
- Right-click OneDrive folders to see real-time storage usage for what's synced locally
Frequently asked questions
Is this the same as Windows Backup?
No, Windows Backup focuses on settings and app lists, while OneDrive sync handles actual file and folder synchronization.
Can I sync different folders on different PCs?
Yes, folder sync selection is configured per device, not account-wide.
Does Files On-Demand delete my files?
No, files remain in the cloud and download automatically when opened; nothing is deleted.
Related settings
- BackupWindows Backup uses OneDrive to continuously back up your Desktop, Documents, and Pictures folders, along with your list of installed apps, saved Wi-Fi network passwords, and select personalization settings like your theme and wallpaper. It's designed to make restoring your setup on a new PC, or after a reset, far less painful than starting from scratch.
- Storage SenseStorage Sense automatically frees up disk space by deleting temporary files, emptying the Recycle Bin after a set number of days, and clearing out old files from your Downloads folder on a schedule you configure. Once set up, it runs quietly in the background so you don't have to remember to manually clean up disk clutter yourself.
- File HistoryFile History is a legacy Control Panel backup tool that continuously copies versions of files in your libraries, desktop, contacts, and favorites to an external drive or network location. Unlike a single backup snapshot, it keeps multiple versions over time, letting you restore not just a deleted file but an earlier version of one you've since changed.
