How would I use native FTP proxying on Windows without an FTP client?

Note: This Knowledge Base article references software which is not maintained or supported by Cisco. The
information is provided as a courtesy for your convenience. For further assistance, please contact the software
vendor.

Configuring the proxy on Internet Explorer (IE) allows IE to use FTP over HTTP (when folder view is
disabled). It does not use native FTP; hence you cannot use the proxy settings. But we can use Windows
Explorer to do native FTP proxying.

Please open Windows Explorer (not IE. example: double click on "My Computer") and use the following
URL in the address bar:

# Example when authentication is disabled on WSA

ftp://USERNAME_FTP%40FTP_SERVER:PASSWORD_FTP@PROXY:PORT

# Example when authentication is enabled on WSA

ftp://USERNAME_FTP%40USERNAME_WSA%40FTP_SERVER:PASSWORD_FTP%40PASSWORD_

WSA@PROXY:PORT

Please keep in mind that this is just a workaround, and may not work in all possible cases. This is under the
assumption that you are using "Checkpoint" for "Authentication Format". Folder view is not part of IE, it is
part of Windows Explorer, which runs outside of IE. The same technique can be used to curl native FTP
traffic through a proxy.

Here is a Microsoft article on how to enable Folder View.
