I discovered a program called "WebDrive" yesterday, it lets you map an FTP site to a Windows drive letter.
It appears to Windows and all Windows apps as a normal drive, so you can open files directly from your ftp site with your html editor. This removes the need for an ftp program
Obviously file-copy/save/open operations are slower but it works really well!
The only drawback is that its not free, I think the full version costs $30 or so. You can download a demo from the site to try it out though!
Hope that helps someone!
