How do I populate a listbox with filenames.
I would like (for example) to have a userform with the listbox on it,
and an "Add" button that opens a Windows Explorer file box, that
allows me to choose a file. When the file is chosen, it is added to
the list box.

As an extra, when a file has been added to the box, double clicking on
the filename would open the file.

Thanks in advance,
