2 Files - must identify same customers in each.

[Henry]

Thanks for reading:
File one is in access xp format. contains 75k records.
Fields are : lastname, firstname, address.
File is from an existing company database.

File two is in excel xp format. contains 20k records.
Fields are : lastname, firstname.
File was data-entry from paper originals.

Process: Compare files, if a name exists on both files
then skip this record, it is already a customer on both
lists. But if the name exists in FILE_ONE and not in
FILE_TWO then we have identified a new customer. Write the
lastname, firstname and address from file one into a new
file called "file_three".

We are attempting to capture the records from file_one
that are not in file_two by using lastname and firstname
as qualifiers. The results are written to file_three.

Files:
file_one : existing file - access xp format
file_two : data-entry file - excel xp format
file_three: new file - the records from file one that are
not found in file_two.

I have not used access in over 8 years. I need the basics
to get this started. I am VERY rusty in this process. ANY
help you can provide is GREATLY APPRECIATED!!!

Thanks
