A Microsoft file hosting and synchronization service.

What you’re seeing is often a sync/cache issue, not always a real second copy of every file. If a folder shows the blue cloud icon and its Size on disk is 0 bytes, it is already online-only, but Windows or OneDrive can still misreport the total size of the main OneDrive folder.
Here are some suggestions you can try:
First, go to OneDrive > Settings > Account > Choose folders, then untick the large folders you do not want on this PC. That removes those folders from the computer, but they stay available in OneDrive on the web.
If the space still looks wrong after that, it is recommended that you reset the OneDrive sync client, because that can fix bad sync status or stuck local cache data. Press Win + R, run %localappdata%\Microsoft\OneDrive\OneDrive.exe /reset, then open OneDrive again from the Start menu.
Also, check the biggest folders with Size on disk, not just Size. It is recommended that you trust Size on disk for the real local usage, since placeholder files can make the total look larger than what is actually stored on C:.
