Column Comparition/Lookup Problem

[lookout2930]

I wish to compare two columns of thousands of file names, Col A and Col D.
Columns D and E are unique pairs, and I'd like to create a file where I can
link Col A and E. When there is a match in Col A with an identical file name
in Col D I'd like to place the value of Col E adjacent to the matches value
in Col C, where the ????'s are. How can this be done.

Col A Col B Col C Col D Col E

One way is to put this in C2 and copy down:
=IF(ISNA(VLOOKUP(A2,D:E,2,FALSE)),"",VLOOKUP(A2,D:E,2,FALSE))
