void Form3_Load(object sender, EventArgs e)

{

this.checkedListBox1.Items.AddRange(System.IO.Directory.GetFiles(@"C:\", "*.*"));

this.checkedListBox1.ItemCheck += new ItemCheckEventHandler(checkedListBox1_ItemCheck);

void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)

Process.Start(this.checkedListBox1.Items[e.Index].ToString());

}

Do you mean to add the filenames as item of the CheckedListBox, click on which to open the file?

void Form3_Load(object sender, EventArgs e)

{

this.checkedListBox1.Items.AddRange(System.IO.Directory.GetFiles(@"C:\", "*.*"));

this.checkedListBox1.ItemCheck += new ItemCheckEventHandler(checkedListBox1_ItemCheck);

}

void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)

{

Process.Start(this.checkedListBox1.Items[e.Index].ToString());

}

Great! Works perfectly!

Sincerely thank you a billion!!
