The user needs to know how to manage local disk space when synchronizing OneDrive files between two computers with different storage capacities.

How to Manage OneDrive Storage When Syncing Two Computers

Product: OneDrive
Device & OS: Windows
Scenario: Synchronizing files via OneDrive between a primary computer with a large hard drive and a secondary computer with a smaller drive using Files On-Demand.
Observed behavior: Opening and saving OneDrive files on the smaller computer downloads local copies, which consumes local disk space and does not automatically revert to online-only.

Before you start

Ensure that OneDrive is running and you are signed in with the same Microsoft account on both computers. Check your current local disk space in Windows Settings to see how much storage is available before managing your synced files.

Solution 1Recommended

Use 'Free Up Space' in OneDrive Files On-Demand

Manually remove local copies of downloaded files to instantly free up disk space without deleting them from your OneDrive cloud storage.

When you open an online-only file, OneDrive downloads a local copy to your device so you can view and edit it. When you save and close the file, this local copy remains on your hard drive. To regain local storage on your smaller computer, you must manually instruct OneDrive to revert the file to an online-only state.

Locate the downloaded files

Open Windows File Explorer and navigate to your OneDrive folder. Look for files or folders with a green checkmark icon, indicating they are currently taking up local disk space.

Select 'Free up space'

Right-click the file or folder you no longer need offline, and select 'Free up space' from the context menu. The icon will change to a blue cloud, confirming the local copy is removed while the cloud version remains safe.

Use 'Free Up Space' in OneDrive Files On-Demand

Do Not Use the Delete Key: Never simply press the Delete key or move the document to the Recycle Bin to save space. Doing so will delete the file entirely from your OneDrive account and automatically remove it from your larger computer as well.

Solution 2

Automate Cleanup with Windows Storage Sense

Configure Windows to automatically make unused OneDrive files online-only when your disk space runs low.

Frequently Asked Questions

Does opening a OneDrive file consume local storage permanently?

When you open a OneDrive file using Files On-Demand, a local copy is downloaded to your device so you can work on it. It will remain on your local drive and use storage space until you manually select 'Free up space' or Windows Storage Sense automatically removes the local copy.

Will deleting a file on my smaller computer remove it from OneDrive completely?

Yes. If you select a file and press the Delete key or move it to the Recycle Bin, it will be deleted from your OneDrive cloud and from all other synchronized computers. To safely remove the file from your local drive only, you must right-click it and choose 'Free up space'.

Can my computer crash if OneDrive fills up my hard drive?

OneDrive itself is designed not to crash simply because it is syncing files. However, if you download too many files and completely fill up your local hard drive, your computer's operating system may become sluggish, and other applications might fail or crash due to the lack of temporary disk space.
