//! Copied files on Windows. arboard adds CF_HDROP to whatever is already on the clipboard, and when
//! Explorer copied a file before, its own formats (Shell IDList Array and friends) stay there and
//! Explorer pastes from those, so Ctrl+V would paste the older file. `ml` empties the clipboard
//! first and marks the files as copied, not cut.
