e) If say 50 files are being copied over 45 files I get a prompt Are you sure you want to overwrite x.x? Yes No Yes to all Cancel. Why isnt there a No to All option. If I dont want to overwrite any file, just append the files that dont already exist, if even 20 files are the same name in both sets I have to answer 20 dialog boxes, has some UI person looked at this long standing issue since 98?

If you keep the SHIFT key pressed when clicking "No" it's like a "No to all."
