I have given the snippet for copying files, you can use same code and add functions for deleting files from System.IO Thanking You,

Hi ankita! You may use following code to list files and folders to treeview control... using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; namespace nListingFoldersToTreeView { public partial class Form1 : Form { public Form1() { InitializeComponent(); LoadFoldersInTreeView(treeView1); } void LoadFoldersInTreeView( TreeView treeName) { treeName.BeginUpdate(); treeName.Nodes.Add( "Desktop" ); treeName.Nodes[0].Nodes.Add( "My Documents" ); treeName.Nodes[0].Nodes.Add( "My Computer" ); treeName.Nodes[0].Nodes.Add( "My Network places" ); DirectoryInfo dirInfo = new DirectoryInfo ( @"C:" ); TreeNode node = new TreeNode (); GetFiles(dirInfo, node); treeName.EndUpdate(); } void GetFiles( DirectoryInfo d, TreeNode node) { DirectoryInfo [] dInfo = d.GetDirectories(); if (dInfo.Length > 0) { TreeNode treeNode = new TreeNode (); foreach ( DirectoryInfo driSub in dInfo) { treeNode = node.Nodes.Add(driSub.Name); // once working I will make it recursive //GetFiles(driSub, treeNode); } } } } } You can use following snippet: // Simple synchronous file copy operations with no user interface. // To run this sample, first create the following directories and files: // C:\Users\Public\TestFolder // C:\Users\Public\TestFolder	est.txt // C:\Users\Public\TestFolder\SubDir	est.txt public class SimpleFileCopy { static void Main() { string fileName = "test.txt" ; string sourcePath = @"C:\Users\Public\TestFolder" ; string targetPath = @"C:\Users\Public\TestFolder\SubDir" ; // Use Path class to manipulate file and directory paths. string sourceFile = System.IO.Path.Combine(sourcePath, fileName); string destFile = System.IO.Path.Combine(targetPath, fileName); // To copy a folder's contents to a new location: // Create a new target folder, if necessary. if (!System.IO.Directory.Exists(targetPath)) { System.IO.Directory.CreateDirectory(targetPath); } // To copy a file to another location and // overwrite the destination file if it already exists. System.IO.File.Copy(sourceFile, destFile, true ); // To copy all the files in one directory to another directory. // Get the files in the source folder. (To recursively iterate through // all subfolders under the current directory, see // "How to: Iterate Through a Directory Tree.") // Note: Check for target path was performed previously // in this code example. if (System.IO.Directory.Exists(sourcePath)) { string [] files = System.IO.Directory.GetFiles(sourcePath); // Copy the files and overwrite destination files if they already exist. foreach ( string s in files) { // Use static Path methods to extract only the file name from the path. fileName = System.IO.Path.GetFileName(s); destFile = System.IO.Path.Combine(targetPath, fileName); System.IO.File.Copy(s, destFile, true ); } } else { Console.WriteLine( "Source path does not exist!" ); } // Keep console window open in debug mode. Console.WriteLine( "Press any key to exit." ); Console.ReadKey(); } } Thanking you,
