Ei, tudo o que eu tenho esse pedaço de código:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim strFileSize As String = ""
    Dim di As New IO.DirectoryInfo("C:\")

    Try
        di.GetFiles("*.*", SearchOption.AllDirectories)
    Catch
    End Try

    Dim aryFi As IO.FileInfo() = di.GetFiles("*.*")
    Dim fi As IO.FileInfo

    For Each fi In aryFi
        strFileSize = (Math.Round(fi.Length / 1024)).ToString()
        Debug.Print("File Name: {0}", fi.Name)
        'Debug.Print("File Full Name: {0}", fi.FullName)
        'Debug.Print("File Size (KB): {0}", strFileSize)
        'Debug.Print("File Extension: {0}", fi.Extension)
        'Debug.Print("Last Accessed: {0}", fi.LastAccessTime)
    Next
End Sub

e funciona muito bem. No entanto, dizendo isso, eu preciso encontrar uma maneira de percorrerTUDO o diretório está na unidade "c" e não apenas na pasta principal.

Alguém tem algum código que pode fazer isso?

Obrigado!
