I see where you are adding items, but I don't see where you are adding sub-items to items.  That is the only way that you can populate the other columns of a ListView.

Another possibility is that you need to have View property set to Detail.

You need to add columns to the ListView, as shown here:

 // Set to details view.
        listView1.View = View.Details;
        // Add a column with width 20 and left alignment.
        listView1.Columns.Add("File type", 20, HorizontalAlignment.Left);
