Powerpoint presentation doubles in size

[50wordsorless]

I received a 5MB PPT and changed some font sizes, rewrote some sections,
added a slide and moved two others and when I saved it it was over 10 MB. I
did ot add any pictures.

While I have never done this before when prompted to save the changes so
that the original author could see them I chose yes. I then got a message
that this wasn't possible, I closed the window and moved on.

It isn't a big deal but I am curious as to what I might have done.

Also when I tried to split the 10 MB file into two pieces, bysaving the
whole piece twice and eliminating the first 18 slides as v1 and the last 18
slides as v2. When I did this I ended up with a v1 at 7.7 mb and the v2 at
7.6 MB.

This isn't a serious or problematic request but rather one of curiousity.

Any thoughts would e helpful.

Hi

Sounds like you have fast saves turned on to me: Tools -> Options -> Save ->
untick 'Allow Fast Saves'. Fast Saves (as far as I understand it) append
your new information to the saved data without removing any of the previous
information data. Result: ever-growing files. I think the idea was that it
would save faster (back in the old days when PCs were slower) and
unfortunately it was turned on by default until version 2007.

If that isn't it try here:
