Hi - I want to develop a program to repeatedly copy a Workbook file
whilst it's opened by Excel (let's say it will do it every 10
seconds).

I've tried this out myself (doing the copies 'by hand' ) and there
doesn't seem to be a problem but are there circumstances in which my
program would not be able to complete the copy ?

I know you cannot delete a file which Excel has open. Is there
anything I should be concerned about where I setup a process which
repeatedly copies an Excel workbook which is in use by Excel ?

thanks
