Architecture :: How To Automatically Load Records To A Db From Files FTP'd To App_Data

The sequence of events is as follows:

1. A piece of software running locally on my pc periodically uploads (approximately every three minutes) to my webserver an xml file comprised of six fields. The file size is < 1K.
1a. The file name is always the same. ie. filename.xml is uploaded. Three minutes later, filename.xml is uploaded again, this time with different contents. I have no control over renaming this file.

2. A chunk of code that parses the xml and inserts the six fields into a database

3. Deletes the xml file

4. Waits for the next xml file to appear in the folder

5. Goto 2.

The locally running software uploads the file without issue. So far, I'm able to parse the xml, do the database insert and delete the file manually by refreshing the browser window and subsequently running the code in the .cshtml file. What I'm having a hard time conceptualizing is what the best way is to set up an automated event/method that watches the folder and when a new file appears, write it to the db without user intervention. Also, where would I put this code? _AppStart? Do I need to start a FileSystemWatcher event on the server somehow? I'm kinda stumped as to how best to proceed.
