[Tutor] File not found error, but it is in the folder!

[Woody 544]

I have a script that worked before I moved it to another folder.  I
cannot understand why I am getting a 'No such file or directory'
error, when the file is in the folder.

Any clues would be much appreciated.  Thanks!

Here is a copy and paste of the script up to the error, output/error
and a check for the file:

SCRIPT:
import os, string, codecs
os.chdir('W:\\BEP\\DOS reports\\Q1 FY13\\BEP_Tool4DOS')

folder = 'W:\\BEP\\DOS reports\\Q1 FY13\\BEP_Tool4DOS\\FY13Q1_responses'
files = os.listdir(folder)

#os.walk(folder)

fy13q1dict = {'country' : 'countryname', 'title':'titlename',
'travel':'traveldata',
'publications':'pubdata','conferences':'confdata','highlights':'higlightdata','upcoming':'upcomingdata'}
countryname = ()
titlename = ()

for i in files:
    fy13q1dict = {'country' : 'countryname', 'title':'titlename'}
    fp = codecs.open(i,mode='rb',encoding=None,errors='replace',buffering=1)
    data = str(fp.read())
    data = data.replace('\xa0',' ')
    data = data.split()

OUTPUT:
>>>
