Then for von Neumanns sake simply try to save it where the user asks you to
and if any error occurs, tell the user.

I mean, there are hundreds of reasons why a file write may fail, why bother
with trying to prevent just one of them? Especially because this hugely
differs between different platforms.

You still have to do error handling anyway, and IMO the user is entitled to
name his own files any way he likes - as long as the operating system  
accepts
it. But after all, the choice of operating system was his, so the blame  
goes
to someone else, not you who prevented the user to create a playlist called
"100% Ginuwine" (yes, I googled).
