“No to all” when moving a folder
When you move files/folders from a folder A to folder B, and folder B already contains some of those files/folders, you’ll see the following dialog box … take a look at it, and tell me what’s missing …

Indeed, there’s no friggin’ “No to all” button!
But there’s a solution: hold down shift when you click “No“, and it’ll be like you pressed the secret “No to all” button! True story!
That’s what the CANCEL button is for!
Not really, “cancel” cancels the whole operation, and no files/folders will be moved. When pressing shift+no, only folders which don’t exist in the target folder will be moved!
