Display LogicalDrives into TreeView Control

Normally in an explorer type treeview, you only display top level folders.
As the user expands a part of that tree, you then load sub folders and then in a listview,any files in that folder
Getting all folders and files at the same time from each drive will stall your program

hi Raj

Try...

string[] drives = System.IO.Directory.GetLogicalDrives();

TreeNode[] nodes = new TreeNode[drives.Count()];
for (var i = 0; i < drives.Count(); i++)
{
    TreeNode node = new TreeNode(drives[i]);
    nodes[i] = node;
}
TreeNode treeNode = new TreeNode("Directory", nodes);

treeView1.Nodes.Add(treeNode);

Can you please give more info

how this will help you.

Look at
System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
