Find and Delete Empty Folder in Computer | Sample program in C#

Do you wonder how many empty folder in your computer? Well, I do. 

It is happen to me when I see the folder name and excited to open it, but then the folder is actually an empty folder. Many times until I found that my computer have alot of empty folder and I need to clean it from my computer.So instead of double click one by one folder and delete it, I decided developed simple application to help me do the job. Here the sample code of my application. 

First of all, i need to choose either GUI or Console., Since I like GUI more than console, so I choose GUI. 

What I needs in the GUI are:- 

  1. The location of the folder/drive
  2. Label to show how many empty folder exist. 
  3. 2 Buttons one to find empty folders, and the other one to delete the folders. 

Here come my GUI application. 




C# code. 

        public Form1()
        {
            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)
        {
            CountEmptyFolder();
        }

        public void CountEmptyFolder()
        {
            string location = textBox1.Text;
            LCount.Text = "-";
            button2.Enabled = false;

            string folderName = Path.GetDirectoryName(location);
            string[] directoryList = Directory.GetDirectories(textBox1.Text);

            ArrayList emptyFolder = new ArrayList();

            foreach (string a in directoryList)
            {
                if (Directory.Exists(a))
                {
                    if (!Directory.EnumerateFiles(a, "*", System.IO.SearchOption.AllDirectories).Any())
                    {
                        emptyFolder.Add(a);
                    }
                }
            }

            LCount.Text = emptyFolder.Count.ToString();

            if (emptyFolder.Count > 0)
            {
                button2.Enabled = true;
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            string location = textBox1.Text;

            string folderName = Path.GetDirectoryName(location);
            string[] directoryList = Directory.GetDirectories(textBox1.Text);

            ArrayList emptyFolder = new ArrayList();

            foreach (string a in directoryList)
            {
                if (Directory.Exists(a))
                {
                    if (!Directory.EnumerateFiles(a, "*", System.IO.SearchOption.AllDirectories).Any())
                    {
                        emptyFolder.Add(a);
                    }
                }
            }

            //delete empty folder            
            foreach (string a in emptyFolder)
            {
                if (Directory.Exists(a))
                {
                    //Directory.Delete(a);
                    Microsoft.VisualBasic.FileIO.FileSystem.DeleteDirectory(a, Microsoft.VisualBasic.FileIO.UIOption.OnlyErrorDialogs, RecycleOption.SendToRecycleBin);
                }
            }

            MessageBox.Show("Successful delete folders.");
            CountEmptyFolder();

        }
