I know what the problem is - @Ulf the OneDrive command has the wrong quotation marks. There are the double quotes that are straight and the double quotes that are curly. The curly double quotes won’t work as they are a different character, so Windows incorrectly thinks that the the curly quote characters are part of the actual path or filename. The two forms of double quotation marks look similar so it is easy to miss the problem.
Discord seems to automatically convert all instances of double quotes that aren’t in preformatted text blocks from the regular double quotes to the curly double quotes. I think when you copy and pasted the OneDrive version from @claude_g_lapalme 's post it wound up turning his regular double quotes into curly ones because he didn’t post the command as preformatted text.
