Windows 10: "Size on disk" means what? OneDrive clarification

In Explorer the Properties menu item reports the size of various Folders as being X but 'Size on disk' as being Y, with Y being often many MB less than X. What precisely does this mean? Is it only related to One Drive and if so why is a One Drive Folder / File shown as having a size on the disk if it is only in the Cloud? The One Drive Folder itself has a size in GB. Does this mean its size in the Cloud, or does it mean many of the files are in fact present on the drive? I did not expect One Drive to have a significant size unless it files have been loaded. As you can see, I am somewhat confused!

Windows 10 - OneDrive

Right click on the app and one of the properties has an option to not automatically start it. Uncheck, restart the computer, and it should stop. If you want to go another step further, find the OneDrive app in the start menu, right click on it and uninstall.

If that is still insufficient, there is a batch uninstaller for OneDrive available online. I can copy the code here if you need it.

Unfortunately, that's how Disk Clean ends.

If you want to check - run it again to see if there's is anything to clean (look at the size on items in the list - small size means only a bit has accumulated since the last run - large means something wasn't cleaned)
Disk Clean / extended goes deep, that's why I suggested that you run it first.

I'd say just move on to the next step: cCleaner, since you're in the cleaning phase.

Ok, onward and upward!

Just for the record, I only suggested the clarification because suggesting everyone has a basic grasp of english simply is not true.
