Hello, I would really appreciate some help here.

I have a master workbook which is updated daily, it contains:

A B C
D
09/09 11:51 25 7543377938 Qtess
09/09 12:06 40 3261241895 Joe
09/09 12:13 70 3787370105 Qtess
09/09 12:42 50 3770339825 Don
09/09 12:49 50 6293323104 Gary

I have a Folder which contains filess with Customer's names identical as
column D
Is it possible to copy row from Master wbk and paste into the last row of
each customer's file if date is different from past entries?

Thanks & regards
