Surely you just need to do the following:
FolderBrowserDialog folderPicker = new FolderBrowserDialog();
if (folderPicker.ShowDialog() == DialogResult.OK)
{
ListView1.Items.Clear();
string[] files = Directory.GetFiles(folderPicker.SelectedPath);
foreach (string file in files)
{
string fileName = Path.GetFileNameWithoutExtension(file);
ListViewItem item = new ListViewItem(fileName);
item.Tag = file;
ListView1.Items.Add(item);
}
}
Then to get the file out again, do the following on a button press or another event:
if (ListView1.SelectedItems.Count > 0)
{
ListViewItem selected = ListView1.SelectedItems[0];
string selectedFilePath = selected.Tag.ToString();
PlayYourFile(selectedFilePath);
}
else
{
// Show a message
}
For best viewing, set your ListView to Details Mode:
ListView1.View = View.Details;
