I like it!

Yes, in the context of memory-limited mainframes being in-the-past, and
our thinking has, or needs to, moved-on; memory is so much 'cheaper' and
thus available for use!

That said, it depends on file-size and what else is going-on in the
machine/total-application. (and that's 'probably not much' as far as
resource-mix is concerned!) However, I can't speak for the OP, the
reason behind the post, and/or his circumstances...
