Absolute path information is required error
<p>Here is my code:</p>

<pre><code>FtpConnection ftp = new FtpConnection(ConfigurationManager.AppSettings["server"], ConfigurationManager.AppSettings["user"], ConfigurationManager.AppSettings["password"]);
ftp.Open();
ftp.Login();
FtpFileInfo[] files = null;
if (ftp.DirectoryExists(some_name))
{
    ftp.SetCurrentDirectory(some_name);
    files = ftp.GetFiles("*.xlsx");
    string fileName = files[0].Name;
}
return;
</code></pre>

<p>Everything works well. The fileName variable has the correct name.
However I get error code 500 even though nothing crashed. The error says: Absolute path information is required.</p>

<p>What does this mean? How to fix it?</p>

<p>When I debugged I noticed that when I expand the properties of files, there is one property Exists, which has the exact same error.</p>
