>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.

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?

Probably the best solution would be a Windows service which uses the FileSystemWatcher class.
