Hello, I was in need of listing subdirectories within FTP and I ended up editing… your **ftp.js** and **ftp.html** code, and implemented this option. If you are interested in using it to update your library, I think it would be interesting :)
Follows the code:
ftp.js:
```
module.exports = function (RED) {
'use strict';
var ftp = require('ftp');
var fs = require('fs');
function FtpNode(n) {
RED.nodes.createNode(this, n);
var node = this;
var credentials = RED.nodes.getCredentials(n.id);
this.options = {
'host': n.host || 'localhost',
'port': n.port || 21,
'secure': n.secure || false,
'secureOptions': n.secureOptions,
'user': n.user || 'anonymous',
'password': credentials.password || 'anonymous@',
'connTimeout': n.connTimeout || 10000,
'pasvTimeout': n.pasvTimeout || 10000,
'keepalive': n.keepalive || 10000
};
}
RED.nodes.registerType('ftp', FtpNode, {
credentials: {
password: { type: 'password' }
}
});
function FtpInNode(n) {
RED.nodes.createNode(this, n);
this.ftp = n.ftp;
this.operation = n.operation;
this.filename = n.filename;
this.localFilename = n.localFilename;
this.ftpConfig = RED.nodes.getNode(this.ftp);
if (this.ftpConfig) {
var node = this;
node.on('input', function (msg) {
var conn = new ftp();
var filename = node.filename || msg.filename || '';
var localFilename = node.localFilename || msg.localFilename || '';
this.sendMsg = function (err, result) {
if (err) {
node.error(err, msg);
node.status({ fill: 'red', shape: 'ring', text: 'failed' });
node.send(err);
return;
}
node.status({});
if (node.operation == 'get') {
result.once('close', function() { conn.end(); });
result.pipe(fs.createWriteStream(localFilename));
msg.payload = 'Get operation successful. ' + localFilename;
} else if (node.operation == 'put') {
conn.end();
msg.payload = 'Put operation successful.';
} else {
conn.end();
msg.message = 'Operation successful.';
msg.payload = result;
}
msg.filename = filename;
msg.localFilename = localFilename;
node.send(msg);
};
conn.on('ready', function () {
switch (node.operation) {
case 'list':
conn.list(filename, node.sendMsg);
break;
case 'get':
conn.get(filename, node.sendMsg);
break;
case 'put':
conn.put(localFilename, filename, node.sendMsg);
break;
case 'delete':
conn.delete(filename, node.sendMsg);
break;
}
});
conn.on('error', function(err) {
node.error(err, msg);
node.status({ fill: 'red', shape: 'ring', text: err.message });
node.send(err);
return;
});
conn.connect(node.ftpConfig.options);
});
} else {
this.error('missing ftp configuration');
}
}
RED.nodes.registerType('ftp in', FtpInNode);
}
```
ftp.html:

<p>Allows LIST, GET, PUT and DELETE of files on a remote FTP server.</p>
<p><code>msg.filename</code> is the path/name of the file on the remote FTP server</p>
<p><code>msg.localFilename</code> is the path/name of the file on the local machine</p>
<p>NOTE: the local machine is where NR is running - this might not be the machine where your browser connects to Node Red.</p>
<p></p>
<p>GET uses <code>msg.filename</code> and <code>msg.localFilename</code></p>
<p>PUT uses <code>msg.filename</code> and <code>msg.localFilename</code></p>
<p>DELETE uses only <code>msg.filename</code></p>
<p>LIST uses only <code>msg.filename</code> and returns an array of the file/folders, containing type, name, sticky, rights(an object), acl, owner, group, size and date.</p>
<p></p>
<p>You can pass <code>msg.filename</code> and <code>msg.localFilename</code> to this node, however values entered in the node will take precedence.</p>
<p></p>
<p>If an error occurs, the error message will come out as <code>msg</code>.</p>
