            string locationToCreateFolder = "E://";
            string folderName = "Upload";
            string date = DateTime.Now.ToString("ddd MM.dd.yyyy");
            string time = DateTime.Now.ToString("HH.mm tt");
            string format = "{0} on {1} At {2}";
            folderName = string.Format(format, textBox1.Text, date, time);
            Directory.CreateDirectory(locationToCreateFolder + "Upload");
            MessageBox.Show("done");
            int CheckBoxRowCounter = 0;
            // Encrypt_and_decrypt.AES a  = new AES();
            for (int i = 0; i < dataGridView1.RowCount; i++)
            {
                if (Convert.ToBoolean(dataGridView1.Rows[i].Cells[0].Value))
                {
                    CheckBoxRowCounter++;
                }
            }
             if (CheckBoxRowCounter > 0)
            {
                if (folderBrowserDlg.ShowDialog() == DialogResult.OK)
                {
                    String folderPath = folderBrowserDlg.SelectedPath;
                    for (int i = 0; i < dataGridView1.RowCount; i++)
                    {
                        if (Convert.ToBoolean(dataGridView1.Rows[i].Cells[0].Value))
                        {
                            string SourceFilePath = dataGridView1.Rows[i].Cells[1].Value.ToString();
                            string SourceFileName = new System.IO.FileInfo(SourceFilePath).Name;
                            string TargetFilePath = folderPath + @"\" + SourceFileName;
                            if (!System.IO.File.Exists(TargetFilePath))
                            {
                                if (System.IO.File.Exists(SourceFilePath))
                                {
                                    System.IO.File.Move(SourceFilePath, TargetFilePath);
                                }
                            }
                            //string Hidkey = dataGridView1[0,2].Value.ToString();
                        //    dataGridView1[0,1].Value= a.EncryptFile("E:\\ on Fri 05.11.2018 At 08.59 AM","E:\\encrypt","Hidkey");
                        }
                    }
                    MessageBox.Show("Selected Files Moved.Refreshing Grid...");
                    FillGridView();
                }

FolderBrowser is a dialog to find a folder name. It has nothing to do with actually processing the files.

How is this supposed to be a "solution" to your question?

There's a whole Cryptography namespace in .NET. To encrypt your files, you need to write code to encrypt them, which you have not, yet. Why would you have a web app that takes a path on the client and then iterates over that folder on the server? If you want to write code to let people manage your file system, you'll need to tell them what it is

I have already written a code for encrypting files i am calling them in the button click, what actually i need is when i click on button i will be selecting(checking) some files in grid view, the selected files need to be encrypted and move to a folder in local system.
