File to File Scenario

Hi

I have done a file to file scenario. My problem is:

I have file in source system ex: file20070428.txt. i will pick this file and place it into destination.Next day in the same source directory i will get one more file with the file name ex:file20070429.txt. using the same file to file scenario i need to pick this file as well. Like this daily file name time stamp will be changed and i have to pick the file how to configure my comunication channel to achive this functionality. Please give me the solution.

Best Regards
