Many thanks vacunita and xwb for your prompt responses. Perhaps I should mention that this my first attempt at a Command Prompt exercise, which will explain any lack of understanding revealed in the course of our correspondence.!! I have been trying out your various suggestions this morning and I have realised something which seems very odd to me.!! When I get to the "Overwrite c:\windows\tempo (Yes/No/All)?" response and try to answer the question, I find I am able to type only lower and upper case y/Y,n/N and a/A.!! All other keys are "dead". This seems to indicate that one of these options is the only valid answer to the question but I have tried them all and the response is always "Bad command or file name." I also got this response when I inserted /y as you suggested xwb. Where do I go from here,please.???
Regards, Alpha.
