SFTP as a folder on Vista

Is there a program available for Vista, that allows me to set up a folder as an SFTP connection to a remote server?

The use case is to have a folder on my desktop, where I can drag/drop/edit files and have my remote location be updated automatically.

I’ve googled this to no avail.  Thanks!

Solution:

ExpanDrive will let you do this.  It has a 30-day trial, but requires a purchase ($39.95) after the 30 days.
