Well new to Office 2007 anyway.

I posted this question in General Questions on 29th March - no reply as yet.

If binary is more efficient speed and space-wise, why isn't it the default
format?

I'm trying to find out what the downside is before I save a majorly
important, large file with heaps of macros in binary. If it isn't the
default there must be a reason - a down side - but I can't find anything in
Help to tell me.

Anyone know?
