A Microsoft file hosting and synchronization service.
Hello,
There are more than one way to go about this.
To find the most efficient way to do so, and also because deletion can sync across device, I have a few questions first.
Do you currently have OneDrive desktop app running on your computer?
How much storage space is currently taken up by Files in OneDrive?
You just want them gone in OneDrive cloud, but you want to keep local files from devices, right?
