Syncing a SharePoint document library lets you work with your files directly in File Explorer, just like you would with files on your computer. Any changes you make are automatically synced to the cloud.
Open your browser and go to https://www.office.com.
Sign in with your work email address and password.
Click the SharePoint app (from the left menu or the 9-dot waffle menu).
Select the site that contains the document library you want to sync.
In the SharePoint site, click Documents (or the name of the document library).
At the top of the page, click the Sync button (you might see a cloud icon with arrows).
If this is your first time syncing, your browser will ask to open Microsoft OneDrive.
Click Open Microsoft OneDrive.
If prompted, sign in again with your work email and password.
After setup, you’ll see the SharePoint site and library appear under OneDrive – [Your Company] in File Explorer.
You can now:
Open files directly in Word/Excel/PowerPoint.
Drag and drop files into the folder.
Right-click any file/folder to Free up space (cloud only) or Always keep on this device (offline copy).
Changes sync automatically both ways — between your PC and SharePoint.
You need Windows 10 or Windows 11 and the OneDrive sync client installed (comes pre-installed on most devices).
If you stop syncing, files will remain in the cloud but no longer update locally.
