Hello friend, There could be n number of levels in a folder structure. As you mentioned that you want to populate List controls with files from each folder in each level. Since you never know the value - n, how are you planning to create List controls? Are you creating List controls dynamically?

Ok. So if you consider Folder structure is nothing but a Tree structure where root node is the top level (n) folder. From root, you have to traverse to it's child node (i.e. n-1 level) and get all the files. Then you have to move to it's child node (i.e n-2 level) to get the files and so on...

I tried to provide a logical solution as I have never tried such problem. Please let us know if you face any challenges to implement it.

can we select the folders by their index ?

hm... finally got separated the files..

and here goes the code for it..(for future friends..)
<pre>
var fbd = new FolderBrowserDialog();
fbd.ShowNewFolderButton = false;

if (fbd.ShowDialog() == DialogResult.Cancel)
return;

string foldername = fbd.SelectedPath;

var dirs = from dir in
Directory.EnumerateDirectories(@" "+foldername )
select dir;
int directoryCount;

foreach (var dir in dirs)
{
foreach (string f in Directory.EnumerateFiles(dir, "*.*"))
{
listBox1.Items.Add(f);

}
directoryCount = System.IO.Directory.GetFiles(@"" + dir).Length;
var lb = new ListBox();
lb.Dock = DockStyle.Bottom;
foreach (string f in Directory.EnumerateFiles (dir,"*.*"))
lb.Items.Add(f);
panel2.Controls.Add(lb);
string m = directoryCount.ToString();
MessageBox.Show(m);
}
</pre>

C#

string[] files = Directory.GetFiles(@"D:\FolderA");
ListBox1.DataSource = files;
ListBox1.DataBind();

string[] folders = Directory.GetDirectories(@"D:\FolderA");
files = Directory.GetFiles(folders[0]);
ListBox2.DataSource = files;
ListBox2.DataBind();

Output would be as follows:

ListBox1:
A1.txt
A2.txt

ListBox2:
B1.txt
B2.txt
B3.txt
