Sending data from a local machine to a remote machine is an upload.
Getting data from a remote machine to a local machine is a download.
The Download method always expects the first parameter to be the path to the file to download from the remote server. The second parameter is the filepath where you're going to save the file when downloaded.
In your case, you're trying to download from a server, but you're getting the UNC path wrong. UNC paths are always \\
address\
share\
filepath. You're missing the share name.
Sorry, but nobody can tell you what that is. You set the server up, so you have to know what the share name of the folder you're sharing on it is.
You're also missing the name of the file to call the downloaded file when it's saved to your local machine.
