Can anyone tell me why when I open a file which I received via email and
select "save as", the filename automatically is preceded by "Copy of" and
then the filename itself? Is there some way to prevent this?

I know it's not a big deal but I can't tell you how many times I have had to
re-name a file not having cuaght this the first time I am saving it over to
my own documents folder.

Thanks in advance...
