If you don’t want to see the delete confirmation dialog box every time you delete a file then that is easy to change. Keep in mind that this warning may save you from accidentally deleting a file though.
To disable this notification message simply right click on the Recycle Bin and choose Properties. Then uncheck the box that says Display delete confirmation dialog and click Ok.
Now next time you delete a file it will go straight to the Recycle Bin without asking you if you are sure.
