[Tutor] exception not raised XP file ?

Due to some sloppy programming on a commercial app :) I have a problem.
I have some directories on an XP machine, I need to know which of these
directories (*.cab_tmp) contains a file that that is being accessed by
another XP program.
I set it up so that a known file (SIZES.DBF) in a known directory is being
accessed by said program.
If I attempt to open said file with wordpad I get the error 'the
document ...SIZES.DBF... is being used by another application and cannot be
So I wrote the following code
posDirNames = filter((lambda x: x[-7:] == 'cab_tmp'),
for dirName in posDirNames:
for fileName in os.listdir(gsrpath + '/' + dirName):
file = gsrpath + '/' + dirName + '/' + fileName
if fileName == 'SIZES.DBF': print file,
f = open(file, 'w')
print fileName, sys.exc_info()
Expecting it to raise an exception when it hits SIZES.DBF because I am opening
the file to write - no exception is raised. I know it is scanning SIZES.DBF
because my if statement picks it up.
Any ideas ?
