Virtual directory of FTP sites in IIS doesn't display any files

view story

http://serverfault.com – I have created a virtual directory in FTP sites in my IIS 5.1. Now in the virtual directory I placed my files so that they can be accessed from a FTP client system. However the virtual directory doesn't show any files. I looked into the properties of the virtual directory and Read and Write check boxes are checked and still I cannot see my files in the directory. What should be done to configure my virtual directory show the files inside the folder? (HowTos)
