Hi Cetin:

Thank you for your response.

I got it to work. The code was looking for .dat files while the file to be copied is an SDF type. Once I change the file name to read "Process*.*", the code found the files and copied them.

The only remaining problem is that the file being copied to should also be an SDF type file. How do I accomplish this? Thank you.
