How To Label Files/Folders/Everything/Anything as NOT 'One Drive'?

I have a couple of files in File Explorer with a red circle, white cross under 'status' and that turns out to mean not enough room for them on One Drive.

I used to dislike One Drive so it's not supposed to be operating on my machine at all. I did things supposed to switch it off. Apparently hasn't worked.

Now I can log in with two different accounts on this computer. One has heaps of room on one Drive (if you call most of 5G 'heaps') the other, true, has less than this file size (1.4G) remaining.

They call all this a 'sync' problem, I think.

But I can't see:

. where to set the file as not to be synced to One Drive.
. where to just tell One Drive to go away.
. where to tell the 'roomy' One Drive account to incorporate that file
. where to tell the 'full' One Drive account to remove that file and switch itself off.

Can anyone help with that, please? The aim is simply to be free of One Drive.

I don't use OD, but don't think you can target individual files - stuff is either in a folder under OD or not. But you can uninstall OD: first shut it down (somewhere under the icon in the task tray on lower RHS), tell it not to start automatically (TM>Startup), then uninstall it: from Control Panel > Programs is the best option, I think. That may not remove it for all users (MS likes to hide copies of the OD install program in multiple locations). I've still got two on my PC and I haven't used OD in years.

thanks for that. I'll do it. :)
