I am a graduate of two universities and hold three degrees so I'm not totally thick all I use the computer for is writing and researching via the Internet and I do not understanding the inner workings of a computer.

I do know how to copy & paste but I have no idea what the terms "source and destination files" mean and therefore have no idea how to select the source file's contents in order copying them or what a destination file is.

My knowledge base is really as restricted as that so when I ask a question on a forum such as this I really do need a simple step by step answer and there is no point in thinking that I hold you level of understanding but thanks for your help.
