Ah sorry Steven i made the change of:

host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0] or 'UnResolved'

to metrites.py isntead of files.py

now i have made both chnages.

you can see the webpage now, eys the one with the cure smile face.

behidn that we should beeen seeing all the files in a table like format 
for uses to downlaod, instead not a single file is being displayed.

here is the print process., actually here is what i have up until now 
after modifications for you to take an overall look.

path = b'/home/nikos/public_html/data/apps/'

utf8_filenames = []

for filename in filenames:
	# Compute 'path/to/filename'
	filename_bytes = path + filename
	encoding = guess_encoding( filename_bytes )

	if encoding == 'utf-8':
		# File name is valid UTF-8, so we can skip to the next file.
		utf8_filenames.append( filename_bytes )
		continue
	elif encoding is None:
		# No idea what the encoding is. Hit it with a hammer until it stops 
moving.
		filename = filename_bytes.decode( 'utf-8', 'xmlcharrefreplace' )
	else:
		filename = filename_bytes.decode( encoding )

	# Rename the file to something which ought to be UTF-8 clean.
	newname_bytes = filename.encode('utf-8')
	os.rename( filename_bytes, newname_bytes )
	utf8_filenames.append( newname_bytes )

	# Once we get here, the file ought to be UTF-8 clean and the Unicode 
name ought to exist:
	assert os.path.exists( newname_bytes.decode('utf-8') )

# Switch filenames from utf8 bytestrings => unicode strings

ima happy that at elaST IT DOES NOT ERRIGN OUT!
