i want that when i will click the button "Save" it will save the mp3 files with the new name in the Desktop.
how can i do it?

there is a code for download.

or if you want here:

namespace WindowsFormsApplication1
    public partial class Form1 : Form
        public Form1()

        private void listView1_DragEnter(object sender, DragEventArgs e)
            if (e.Data.GetDataPresent(DataFormats.FileDrop))
                e.Effect = DragDropEffects.Copy;
        private void listView1_DragDrop(object sender, DragEventArgs e)
            string[] handles = (string[])e.Data.GetData(DataFormats.FileDrop, false);
            foreach (string s in handles)
                if (File.Exists(s))
                    if (string.Compare(Path.GetExtension(s), ".mp3", true) == 0)
                else if (Directory.Exists(s))
                    DirectoryInfo di = new DirectoryInfo(s);
                    FileInfo[] files = di.GetFiles("*.mp3");
                    foreach (FileInfo file in files)
        private void AddFileToListview1(string fullFilePath)
            if (!File.Exists(fullFilePath))
            string fileName = Path.GetFileName(fullFilePath);
            string dirName = Path.GetDirectoryName(fullFilePath);
            if (dirName.EndsWith(Convert.ToString(Path.DirectorySeparatorChar)))
                dirName = dirName.Substring(0, dirName.Length - 1);
            ListViewItem itm = listView1.Items.Add(fileName);


        private void listView1_SelectedIndexChanged(object sender, EventArgs e)


        private void button1_Click(object sender, EventArgs e)
            for(int item = 0; item < listView1.Items.Count; item++)
                    listView1.Items[0].Text = textBox1.Text + " 1";
                    listView1.Items[1].Text = textBox1.Text + " 2";
                    listView1.Items[2].Text = textBox1.Text + " 3";
                    listView1.Items[3].Text = textBox1.Text + " 4";
                    listView1.Items[4].Text = textBox1.Text + " 5";
                    listView1.Items[5].Text = textBox1.Text + " 6";
                    listView1.Items[6].Text = textBox1.Text + " 7";

        private void button2_Click(object sender, EventArgs e)
              //This is the Save Button

not so well, i mean i did it but i have some problems so i need you for help me


look the program is for my dad, he asked me to do something like that for him,
so i started and i was stopped at this point i have problem with my code to save file with new name


Ok, I saw this post of yours, and what I want now is a decent explanation of the problem. I will not even look into code of yours, but I need some words what you need to do. Simple.


again this is me IDC_Sharp (new account) hh
ok i made a listView, a textBox, and 2 buttons:

- listView1
- textBox1
- button1
- button2

now i made the code that you can drag mp3 files from your computer into the listView
the listView shows the name and the path (c:/what ever/what ever/song.mp3)
when i click button1 it's change the name of the items in the listView to the text of the textBox and it's add number i mean
if the song call "ABC"
and i put in the textBox "DEF"
and the index is 0
this specific item will change his name to "DEF 1"; (the indexes starts with 0 so the name will be everytime bigger with 1 - you can see the code above).

Until now i made everything ok.


now i want that when i will click on button2 it will save those mp3 files with there's new name somewhere else.
and i had problem with the code so i came to here


hdd? what is that mean?
but yes i mean that i want it will copy the files to other location with new name


hdd = hard disc drive :)
About your code:
You can create a FileInfo array, and save them on the other location.
Does your listView has only one column or two? (fileName, and full file path)

I did a code, but didnt test it, becuase I did use any real files in example:

private void button1_Click(object sender, EventArgs e)
            for (int i = 0; i < listView1.Items.Count; i++)
                var someFile = new FileInfo(listView1.Items[i].Text);
                File.Move(someFile.FullName, listView1.Items[i].SubItems[1].Text);
                //the point is, that you have to specify two things inside the brackets:
                //1. Source file name (path where is the file now)
                //2. New file path!

actually this is where i was stopped in the beginning.
your code mean that it will copy them with the new name to the same location of the file
i want that it will copy them in the Desktop
so i made 1 more column.
every item will got 1 more subitem that have always the text "C:/Users/what ever/Desktop"
so i tried to save them but there is more problem like what it was error about your code
Could not find file
'C:\Users\What Ever\Desktop\MusicFilesMixer\MusicFilesMixer\bin\Release\song 1.mp3'


Nevermind i finally success to do that!!! it's was a fucking silly mistake!!
hhh thank you anyway.
if you want to the code i will send you
