In all cases it is FOR loop that should go through ALL the files. Therefore I am looking for the SORT by date approach, then I would use WHILE loop instead.

>Have you done any testing to find out what part of the code that is "slow". I don't like "old" VB6 functions that you can import in VB.NET so I figured I would write a little code myself to test (again it seems pretty quick but I don't have that many files). Here is the code I used (keep in mind it has no error handling and no error checking (it took me about 10 minutes to write (I got interupted by a phone call <s>)))
