1. Please state what application and version you are doing this in.

2. If I understand correctly, what you are asking for is the ability to have a UserForm lose its focus so someone can give Windows Explorer the focus, select files in Explorer, drag them back to the UserForm, give focus back to the UserForm, extract the variable contents of what is being dragged (that is, the string names) and put those string names into the listbox.

Correct?
