Basically, you would just get the list of files using this code:

http://www.thescarms.com/dotnet/listfiles.aspx

Imports System.IO

Dim strFileSize As String = ""

Dim di As New IO.DirectoryInfo("C:\temp")

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

Dim fi As IO.FileInfo

For Each fi In aryFi

strFileSize = (Math.Round(fi.Length / 1024)).ToString()

Console.WriteLine("File Name: {0}", fi.Name)

Console.WriteLine("File Full Name: {0}", fi.FullName)

Console.WriteLine("File Size (KB): {0}", strFileSize )

Console.WriteLine("File Extension: {0}", fi.Extension)

Console.WriteLine("Last Accessed: {0}", fi.LastAccessTime)

Console.WriteLine("Read Only: {0}", (fi.Attributes.ReadOnly = True).ToString)

Next

Instead of writing to the console, write to a 2-dimensional variable, then you just loop through them.

If this is not enough to get you there, let me know an I will try to write some custom code, but it might take a few days to find the time.
