Morning all,

I am downloading a file that gets loaded sometime after 10PM and we  
never know what time it will be put on the server. I have my code look  
for the file and if it does not match my test then sleep for 1800ms and  
then check again. I have the code getting the file I need just fine but  
when I add the sleep, it just sleeps straight away when I know the  
correct file is there. Can you guys have a look and let me know where  
I’m going wrong?

Also if there is a better way to just look at the FTP directory and see  
if the file is there I am open to any ideas.

Thanks in advance,  
Tim
