    File format (PPT 97/ PPT 2002)

    When I read the Powerpoint 2002 help and Microsoft web site I am totally confused.

    Is there any difference in the file format between Powerpoint 97 and Powerpoint 2002? Do I have to do anything to my file in PPT 2002 so that it can be read in PPT 97?

    The help talks about a file format for PPT95, another for "PPT95 and PPT97-2002", and a PPT2002 standard. The PPT95 and 97-2002 file format is said to be HUGE with 2 copies of the PPT presentation embedded, so that is not a great solution. We just want a simple file to share between PCs running PPT97 and PPT 2002. Upgrading everyone in our organisation to Office XP will cost over AU$1,000,000...just out of the question.

    There are a lot of little differences between presentations in 97, 2000 and 2002. The "What's New" section of the help files or online sales materials will give you the general idea; for example, among the new features of PPT02, the following seem to involve actual changes in the file itself:
    <hr>Collaborative online reviews
    Microsoft PowerPoint and Microsoft Outlook work together to help you e-mail a presentation...
    Comments also work with the new reviewing feature. They're color-coded by reviewer...

    Animation effects and animation schemes
    PowerPoint has new animation effects, including entry and exit animations, more timing control, and motion paths...
    Animation schemes let you apply a pre-designed set of animation and transition effects to your entire presentation...

    Better organization charts and new diagram types
    Organization charts now use the drawing tools in PowerPoint...

    Multiple design templates per presentation
    PowerPoint 2002 supports having more than one design template in your presentation...

    Text AutoFit improvements
    You can now turn text AutoFit on or off per placeholder, giving you a finer degree of control...

    Password protection
    A top feature request, and now it's here. Just like in Word, you can set a presentation to open with a password, specifying read-only or read-write access to the file.

    Embed a subset of the characters in a font
    File sizes stay smaller when you embed fonts thanks to a new option that lets you include only the characters that are used in the presentation (not the entire font). This option is available with certain fonts with large character sets, such as Japanese and Unicode fonts.

    Improved fidelity of pictures and drawings
    In Office XP, Word, Excel, PowerPoint, Microsoft FrontPage, and Microsoft Publisher are using an improved graphics system (GDI+). With this new graphics system, shapes and WordArt have smoother outlines and adjustable levels of transparency with true blending. Digital pictures stay sharper and clearer when you resize them.<hr>
    When an earlier version encounters these new features, it could ignore them, mess them up, or choke. I really don't use PPT enough to predict from feature to feature which it will be. The only perfectly safe approach would seem to be to only use PPT 97 features in all presentations.

    But... I read on this very board that Microsoft is expected to release a new viewer utility that will allow your PPT97 users to view PPT00/02/03 presentations in the manner in which they were intended to display. Maybe that will help...

    Last but not least, please ignore PPT 95, you definitely don't want to save in that format. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Thanks for the reply.

    How then, can I save a file from PPT2002 and be sure I can open it OK in PPT97? If the Office XP file uses the new features, will I be able to open it in PPT 97?
    Word 2002 has a feature to ensure the file is Word 97 compatible.
    Excel 2002 is the same format as Excel 97.
    How do I do it for PPT?

    The issue of a viewer is interesting, but not as important as the ability for different people to work on preparing the one presentation. Really I want a converter like is available for Word 2002 to Word 97.

    Simply choose to save in PPT 97 format (see picture).
    Even if you've used some of the new PPT2002 features you'll be able to open the file. But of course, the new features are supported in older versions. The warnings are their in case you decide to make some nifty new animation function the centerpiece of your presentation and then find out that it doesn't work just as your presentation starts!

    Re: File format (PPT 97/ PPT 2002)

    Actually, the "&95" part on the back of that save option is the killer. There is no basic "save as 97" option because it's not needed.

    PPT 97, 2000, and 2002 can all read the same file formats. So can 2003, for that matter. You don't have to do anything special when saving, and please please please do not use the save as "97-2002 AND 95" option, as that will cause you more problems than it will solve.

    So the upshot is that PPT 97 will open PPT 2002 files just fine. It won't choke. If there are new features which have been used in the 2002 file which 97 cannot interpret, it will simply not show them. (Good examples would be some of the new animations and transitions.)

    To help avoid these features, you can open Tools/Options in PPT 2002 and turn off the new features. There are 3 on the Edit tab in Tools/Options, I think it is. (If it's not there, check Tools/Customize and Tools/Autocorrect. Sorry, I'm on a 2000 machine here, so I can't check.)

    Finally, PPT 97 will indeed choke if you apply a password to the PPT 2002 file. The recipient will see an error message something like, "PPT cannot open the type of file represented by <file name>." So it may *seem* as if the file is corrupt or if 97 cannot open 2002 files, but that's not the case. Just eliminate the password protection on the 2002 end and all will be well.
