I'm currently working hard on the FileSystem support for Xceed FTP for .NET, and I had to share with you a screenshot of one of my tests. My XceedBox.NET sample is now fully supporting FtpFile and FtpFolder mapping.

As you can see, my working folder is a zip file located in a folder on an FTP server. The "type" command above has no idea what kind of file it is displaying. It receives an AbstractFile, gets a Stream on it via OpenRead, reads and displays the contents. That AbstractFile is actually a ZippedFile found in a ZippedFolder constructed around an FtpFile found in an FtpFolder.
