Or, really crude - when you see the file, record the time and the file size, but don't attempt to process it yet. Wait for a short interval, then check the size again. If it's changed, wait again. When it gives the same size after a delay period, assume all the data is there. This isn't a good method, but it's simple to implement and will reduce the occurrence of attempts to process a file which is still in transit/ -- Jim Segrave ([EMAIL PROTECTED]) -- http://mail.python.org/mailman/listinfo/python-list
