My testing showed that IB won't overwrite an external file using the
external table facility and a quick read of the source (jrd/ext.c)
appears to say so too (not that I am that confidant about my source
reading). While this makes no difference to the ability of IB to
create trojan horses, I am curious: Can IB overwrite non-gdb files?
