Buenas.
Estoy intentando averiguar como es el tema de las conexiones a FTP.
De algun lado de internet saque este codigo:

Código: Text

1.  
2. Private Sub Command2_Click()
3. Dim El_Host As String
4.  
5.     If txt_Remoto = "" Then
6.        MsgBox " No hay archivo para descargar", vbInformation
7.       Exit Sub
8.     End If
9.    
10.         List1.AddItem " ..Descargando "
11.         'Asigna la Url, es decir el nombre del Host FTP
12.         El_Host = "ftp://" & txt_servidor
13.        
14.     With Inet1
15.        
16.         .URL = El_Host
17.      
18.         'nombre de usuario y password de la cuanta FTP
19.         .UserName = txt_Usuario
20.         .Password = txt_Pass
21.    
22.         'DEscarga el archivo indicado con el comando Get
23.         Call .Execute(, "Get " & txt_Remoto & " " & txt_local)
24.         DoEvents
25.        
26.      End With
27. End Sub
28.  
29.  

Al parecer aca toma un archivo especifico que estaria en el ftp y lo descarga en alguna ruta.
Realmente este ejemplo todavia no lo lleve a la practica, espero que funcione.
Yo lo que quisiera saber es como haria para bajarme todos los archivos que esten dentro de un directorio.

Espero que puedan ayudarme.

Saludos.

Salu2. Aquí te dejo un ejemplillo:
