In Windows 10, running as administrator:

I've tried various invocations of FileUtils.move, passing file/directory objects or strings, and everything seems to end up the same. Am I using this incorrectly?

---

It appears I was using this incorrectly. File.new actually opens the file, which prevents it from being moved. If that's as intended, I guess this is not a bug.

Windows disallows removing open file unless it is opened with FILE_SHARE_DELETE flag.
Close file before FileUtils.move.
