WindowsError: [Error 145] The directory is not empty: u'R:\\calibre library\\Under The Dome (v0.5) (html)\\Under The Dome (4045)'


After I hit okay on the error message popup and then hit okay to convert the files converted fine. I'm just not sure what this error message means? And if I'm ruining something by continuing to ignore the messages?

I'd appreciate any and all help.
