- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Managing cloud storage space and synchronizing folders between Microsoft OneDrive and a local computer.
- Observed behavior
- The reported file size on the OneDrive web portal is much larger than the local PC's OneDrive folder size due to unsynced or unchecked folders.
Ensure that the OneDrive desktop application is running on your PC, indicated by the cloud icon in the Windows taskbar, and that you are connected to the internet.
Adjust 'Choose Folders' Sync Settings
Review and modify your OneDrive synchronization settings to see which cloud folders are excluded from downloading to your local PC.
OneDrive allows users to save local disk space by keeping certain folders only in the cloud. If folders are unchecked in your sync settings, they will count toward your online storage quota but will not appear on your PC, causing a size discrepancy.
Click the OneDrive cloud icon located in the Windows taskbar notification area. Click the gear icon (Help & Settings) and select 'Settings'.
In the OneDrive Settings window, click on the 'Account' tab from the sidebar menu to view your storage usage and account details.
Click the 'Choose folders' button. A list of all your OneDrive cloud folders will appear.
Look for any folders that do not have a checkmark next to them. These unchecked folders exist online and take up cloud storage space, but they are not downloaded to your PC.

Verify OneDrive Account Details
Check your account type and online portal to understand exactly how your storage quota is being consumed.

Frequently Asked Questions
Do unchecked OneDrive folders get deleted from the cloud?
No, unchecking a folder in the 'Choose folders' menu only removes it from your local PC to save hard drive space. The files remain safely stored in your online OneDrive account.
Can I access unsynced files without downloading them to my local drive?
Yes. You can access, view, and manually download any unsynced files by signing into the OneDrive web portal through your internet browser.
Why does my OneDrive taskbar icon show a sync error?
Sync errors typically occur if you have run out of local hard drive space, exceeded your cloud storage quota, or are experiencing internet connectivity issues. Click the taskbar icon to view the specific error message and take corrective action.
