hice un filemanager... funciona todo bien... pero solo en C:\ o donde este el server...
mi duda era como hacer a detectar si hay otras unidades...
yo probe en mi computadora y si pongo F:\ tb me muestra sus archivos y cosas... pero no tengo como saber en una computadora remota... si existe o como se llaman las otras unidades...
aclaro q busque en el buscador.. pero siempre me decia q usara mas palabras.. xD y no sabia ya como combinarlas xD
SALUDOS
2 Funciones API,
Private Declare Function GetLogicalDrives Lib "kernel32" () As Long
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long
Con la primera obtiene la letra de las unidades y con la segunda el dipo, digase si es disco duro, unidad de cd, etc..

muy buenas ambas respuestas :) ahora me voy a poner a adaptarlo a mi programa :P
GRACIAS!

modifico para no postear de nuevo y reabrir el tema... x si alguien lo lee en un futuro le digo como simplifique el codigo para lo q yo necesitaba:
Private Declare Function GetLogicalDrives Lib "kernel32" () As Long
Dim Drives As Long
Dim i As Long
Dim LasUnidades As String
Private Sub Form_Load()
Drives = GetLogicalDrives
For i = 0 To 25
If (Drives And 2 ^ i) <> 0 Then
LasUnidades = LasUnidades + " " + Chr$(65 + i)
End If
Next i
MsgBox LasUnidades
End
End Sub
