If you don't know a way to get the files in the directory and write them to another file name, Please don't comment.

Dim files As String() = Directory.GetFiles(directoryPath)
DataGridView1.Columns.Add( New DataGridViewTextBoxColumn() )
For Each f As String in files
    Dim fa As String() = {f}
    DataGridView1.Rows.Add(fa)
