Usenet Explorer

How do I make a filter that:

List all posts of a certain search-criterium (subject contains *postname*)
But only select a certain extension for download (only download *.exe)

So I will be able to manually mark par-files for download when needed?

Thanks,

G00fy.

subject contains postname "extract"
subject contains .exe "extract"

if several extensions .exe|.mp3|.avi ... (boolean wildmat)
