You can create a Windows service that hooks into the Windows file monitoring system. When the file arrives, an event will be raised to the service to process it.

>I wasn't sure how to classify this question, but I have a situation where I want to have a process (already written) run when a file is populated into a directory on my server. Basically, it is an import process that takes a file and loads it into the database. The file will be sent to the directory by partners via FTP.

>How should I create this? Should I create some kind of 'listener' process (if so, how is this accomplished?) that kicks off the import process when a file exists or create a console app that runs every minute or so and checks for the existence of said file in the directory and then run the import process when the file exists?
