The method here is to move the data from the two input files into to arrays that you can move through quick with code. Use two loops (outer loop for array data from File1 and an inner loop for the array data from File2) and look for common data. Put the data that is distinct(not common) into another array and when you are done with the looping. Load the listbox from the third array. John
