IOS created folders - illegal characters in Windows

as the title says - when an IOS device makes a folder - it seems that windows sees something ‘illegal’ about it, and won’t sync it until a user logs into the web interface, and re-types the name.

any clue as to what’s up here?

What characters are in the foldername that are illegal? Can you post us such a folder name? It can be leading spaces or other things that are not supported by the Windows file system.

That’s the thing… it doesn’t appear so.

And now I feel like i’m lying, had a look at the machine complaining on Tuesday - there are no errors today… I’m going to that site Monday, I’ll see if anything has changed since. egad.
