i've found a simpler approach, in fact, this list of pathes is entered
by the user using a File/folder chooser window, then instead of walking
a three or something else, xhen the user enter a new path right now i
check only if this path is allready taken into account by :

files.each { |f|
  f_to_s = f.to_s
  @forbiddenList << f_to_s unless @forbiddenList.include_path?( f_to_s )
}

with : 
files the File(s)/Folder(s) entered by the user ;
f.to_s converting NSString to Ruby String (NS stands for NextStep) ;
Array#include_path?( a_path ) being :
class Array
   def include_path?(path)
     self.any? { | x | a_path.rindex(  x, 0 ) }
   end
end

the only thing i dislike is in that pathes have nothing to do with
Array,i must rexrite this part.

yes right, here i'm embarassed because my code isn't "pure" Ruby, it's
RubyCocoa (a bridge between Cocoa/ObjC on Mac OS X) and in RubyCocoa the
Cocoa methods like :

NSOpenPanel#beginSheetForDirectory:file:types:modalForWindow:modalDelega
te:didEndSelector:contextInfo:

are translated, on the Ruby side, in :

beginSheetForDirectory_file_types_modalForWindow_modalDelegate_didEndSel
ector:contextInfo( ... )

then "_" replaces ":" and still camelized...
