Well, you just need to use the GetDirectories method of the DirectoryInfo object to get an array of all directories in the current directory. The you can just add to the listview calling GetFolderSize for each directory in the array, something like this:-

VB

Public Sub LoadDirectoriesInListView(ByVal currentDirectoryValue As String)

        ListView1.Items.Clear()
        currentDirectory = currentDirectoryValue
        Dim currentDirectoryInfo As DirectoryInfo = New DirectoryInfo(currentDirectory)
        Dim directoryArray As DirectoryInfo() = currentDirectoryInfo.GetDirectories()
        Dim dir As DirectoryInfo
        For Each dir In directoryArray
            Dim lvi As New ListViewItem(dir.Name)
            lvi.SubItems.Add(GetFolderSize(dir.FullName, False))
            ListView1.Items.Add(lvi)
        Next

    End Sub

Then you just call it like this:-

LoadDirectoriesInListView(currentDirectory)

Hope this helps

Nice codeee but i am unable to define "GetFolderSize"

In line:
lvi.SubItems.Add(GetFolderSize(dir.FullName, False))

Please could u possibly advise.

GetFolderSize is the function you defined in your question above, that returns the size of the folder/directory.

You could just call the LoadDirectoriesInListView function from your timer tick event.
