When you copy, move or delete a group of files you often receive prompts that ask if you're sure you want to take a specific action; Are you sure you want to move that read only file? This folder already contains a file named 'abc'. Would you like to replace the existing file? If you notice in the dialogue prompt that Windows shows, there is an option for 'Yes to All', but not an option for 'No to All'. However, although Windows does not display this option, it still exists in quasi-keyboard shortcut form. When a Yes to All/No prompt appears,holding the Shift key and clicking no has the same effect as 'No to All'.This means that across the board Windows will not overwrite, copy or delete any file in that particular operation for which you have opted 'No to All'. Windows will prompt you for each type of operation, once for move a read only, once for overwrite confirmation, but only once for that particular action. It behaves the same as the 'Yes to All' option presented in the standard Windows dialog with a 'no' instead of a 'yes.'
