I ran into problems when using fdir (1!:0) when the files were larger than 2
gig. The size of the file is wrong as is documented. I addressed this by
using bigfiles and it worked well until I tried to get the size of a file
that was open by another application. Then bfsize_jbf_ fails. What confuses
me is that somehow 1!:0 can retrieve the size of the file (though incorrect)
even though it is open to another application. As best as I can tell all
file tools provided by Microsoft require file handles implying that the file
has been opened.
So how does 1!:0 get the file size for files open to other applications? It
would be nice if bigfiles could use the same technique.
