Hello again,

Wow what a lot of replies.

OK here goes. I know little about win 2000 so when I

My computer > C > My documents I assumed that was where the my documents 
folder was,
Having gone through what you guys said I also have

C:\Documents and Settings\Administrator\My Documents

So I copied memo.txt to C:\Documents and Settings\Administrator\My 
Documents, ammended my code

memo_file = 'C:\Documents and Settings\Administrator\My Documents\memo.txt'
csv_file = 'c:\data.csv'

def palm_conv():

# The money sheet
map1 = [[0]*5 for n in xrange(42)]
map1_count = 6
# The time sheet
map2 = [['']*7 for n in xrange(75)]
map2_count = 0

day_map = {'sun':0, 'mon':1, 'tue':2, 'wed':3, 'thu':4, 'fri':5, 'sat':6}

sh_offset = 0
ot_offset = 0
ca_offset = 0
pa_offset = 0
su_offset = 0

time_slot = 0
text_slot = 0

memo = open(memo_file, 'r')

count = 0
raw_line = ' '

And got the following again ...

Traceback (most recent call last):
File "C:\Documents and Settings\Administrator\Desktop\palm.py", line 
268, in ?
File "C:\Documents and Settings\Administrator\Desktop\palm.py", line 54, 
in palm_conv
memo = open(memo_file, 'r')
IOError: [Errno 2] No such file or directory: 'C:\\Documents and 
Settings\\Administrator\\My Documents\\memo.txt'

So I tried your test code & got ...

 >>> import os.path
 >>> print os.path.expanduser('~/memo.txt')
C:\Documents and Settings\Administrator/memo.txt
 >>> f = open(os.path.expanduser('~/memo.txt'))
Traceback (most recent call last):
File "<pyshell#15>", line 1, in ?
f = open(os.path.expanduser('~/memo.txt'))
IOError: [Errno 2] No such file or directory: 'C:\\Documents and 

Now starting to doubt my sanity I again re-checked C:\Documents and 
Settings\Administrator\My Documents
and yes I do have a memo.txt there.

In C:\Documents and Settings I have the folders administrator, all users 
and compy, I put a copy of memo.txt in
compy as well & changed my code, same problem

Any ideas
