Yes, but the point that I'm trying to get across is that the earlier you 
make sure that you've got full access to the files (i.e. all directories 
in the path exist, the file either exists and is writable or you create 
it from a template) the easier you make life for yourself. If having the 
file is absolutely essential then check for it before you even open the 
main form and bomb if it's obvious that there's a problem.
