If you just don't want '._' prefix then match the File.basename with  
regex and
do an if.

Find.find('/Volumes/MYBOOK/stuff/') do |f|
   puts(f) if not File.basename(f).match(/^\._/)
end

Find.find(`pwd`.chomp) do |f|
   puts(f) if not f.match(/^\._/)
end


If you don't want to see all hidden files you can use Rake::FileList  
instead
of using Find.find.
irb> Rake::FileList['**/*']
=> ["bfs_listing.rb", "bla", "bla/bla", "bla/bla/bla", "bla/bla/bla/ 
bla",
     "bla/bla/bla/bla/fasel2", "bla/fasel", "test1"]

Here my example dir tested with your find
irb> Find.find(".") do |f| p f end
"."
"./test1"
"./bla"
"./bla/fasel"
"./bla/bla"
"./bla/bla/bla"
"./bla/bla/bla/bla"
"./bla/bla/bla/bla/fasel2"
"./bla/bla/bla/bla/._nein"
"./bla/bla/bla/._nein"
"./bla/bla/._nein"
"./bla/._nein"
"./bfs_listing.rb"
"./.test"
"./._nein"
=> nil

The behaviour of Rake::FileList is that what I think you want, but  
you can
implement your own tree traverse if you want.
