An enhanced Windows Explorer application which consists of a tree view where someone can see the files available in the existing drives up to certain levels.

Introduction

The aim is to create an application which (is enhanced Windows Explorer) consists of a tree view where someone can see the files available in the existing drives, up to certain levels. (In this case, 4). You can easily change it to any level you want. Also, when someone selects a file from the tree view, we need to display the different properties of this file in the labels in the group box.

I create a Windows application with a tree view showing the files in the drives as in fig 1.The user can expand them up to 4 levels to see the files/directories. The details of the selected file or folder like the file name, date created, size etc. are shown in the labels in the Details GroupBox (Fig 1). Also the Data GroupBox contains a multi-line text box which shows the contents of the selected file.

This function quits after 4 levels of any branch. Actually Windows Explorer does the same thing. Initially, it loads only couple of levels and when you click on some branch, it reloads that branch to deep levels.

If you try to load all the levels, then it's going to take up to 2-5 minutes depending upon your machine speed.

C#
private void FillDirectory(string drv, TreeNode parent, int level)
{
    try
    {
        // I want to go only upto 4 level.
        level++;
        if (level > 4)
            return;
        DirectoryInfo dir = new DirectoryInfo(drv);
        if (!dir.Exists)
            throw new DirectoryNotFoundException
                ("directory does not exist:"+drv);
            foreach(DirectoryInfo di in dir.GetDirectories())
        {
            TreeNode child = new TreeNode();
            child.Text = di.Name;
            parent.Nodes.Add(child);

            FillDirectory(child.FullPath, child, level);
        }
    }
    catch(Exception ex)
    {
        ex.ToString();
    }
}
