Sorry, my mistake.

Does it have to run on platforms other than XP? I forget offhand if 
all older Windows versions have an Application data folder. But what 
I've done if specialFolderPath returns empty is to just use the 
application folder. This assumes that the user can write to Program 
Files, but I think it's a fairly safe assumption in such cases.

I think that specialFolderPath will return empty if the folder 
doesn't exist, so this part may be unnecessary. But don't take my 
word for it.

Cheers
