shutil.move, permission denied, why ?

  Thanks for the idea. It helps.

On this part of the code:
(see <Xns94C49F78550F2stefninalussinanorg at 212.27.42.71> for full test 
script) 

    def read(self,filename):

        from _xmlplus.sax.sax2exts import XMLValParserFactory
        parser = XMLValParserFactory.make_parser()

        dh = DefaultHandler()
        
        parser.setContentHandler(dh)
        parser.setErrorHandler(dh)
        
        f = file(filename,'r')

        
        print 'TestReader B'
        system('handle.exe xml')
        r=raw_input('Press\n')

        
        try:
            parser.parse(f)
        finally:
            print 'CLOSE FILE'
            parser.close()
            parser.reset()
            f.close()
            print 'TestReader C'
            system('handle.exe xml')
            r=raw_input('Press\n')
            print f.closed
            
            
        return 1


I have the following output for a "bad file"
(parser throws exception during parsing):

... while, for a file which is correctly parsed I have this output:

TestReader B

I am not sure I am interpreting this correctly... 
Even if file is closed (as say f.closed),
handles are still there ?

And if problem comes from the parser (PyXML), I guess I will somehow 
workaround the problem, as I dont want to dig into PyXML code. :) 
(Unless you have some other idea.)
Well, I will also test this week-end if problem also happens on Linux.
(as this code is supposed to run only on Linux,
I will just skip this problem if it works fine on linux)

Thanks for your suggestion.
