Loop Through Top Level Folder In Mapped Drive And Give Total Count Of Files And Total?

I am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:

Folder Path Size(GB) Count of Files
N:Clients 0.53 308

where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.

This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.

1) I would like to see in my spreadsheet the following by only select the network drive n:

Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105

2) I would also like to know if this is the faster method.

3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.

4) I would like to see the folder name, size of folder and count of files in the listview.

Here is the code:

Imports Microsoft
Imports Microsoft.Win32
Imports Microsoft.Win32.Registry
Imports System.Collections
