Thanks for the replies! filepath.Ext()! Didn't occur to me to try that. It goes to show that the standard library really is pretty complete.

Dirk, I like the for ext := range m { sort.Strings(m[ext]) } solution then I wouldn't need to have a separate sort in each "print" function, it's much clearer that way.
