export a workbook to specific loc on other computer via internet
 

i work for a company with about 18 branches. i have a workbook that i design
and maintain at my side. i regularly need to change products and all kinds of
things in it. then i email it to the other branches. they then need to save
it to a specific location on theyr computer.

are there any way that i can easily send this from my side to be in that
location? and secondly are there a way that the 'opening' wich they got on
theyr sheet be carryied over to the one that i then send?
