macOS – Invalid Characters for a File Name

Andrew Mortensen’s duti is a CLI that will list UTI handlers:

• -d <uti> lists the default handler;
• -l <uti> lists all registered handlers.

See the man page for duti.

EDIT: as Lri points out in this answer, duti does not seem to list all possible applications (possibly because it does not take account of UTI inheritance? That would be a matter for further inquiry). His recommended solution, AllApllications would obviously be a better answer.

Microsoft has an Article about hard to delete files.

Most of the time for me, prepending the path with \\?\ does exactly what I want. So you could try del "\\?\c:\path\Kanno, Yoko - Where Does This Ocean Go?.mp3"

There is also \\.\ and I don't know what the exact difference to \\?\ is.

Both prefixes seem to disable some checks and/or make del use lower level APIs than the usual Win32 API.
