Hi,

Re: V 2003 - Save as file type

(1) Can you point me to an article/tutorial explaining all the file types
please?

(2) I save one presentation to MHTML (single file web page) and HTML (web
page) respectively. I see that the size of MHTML is many times larger than
HTML. Is the small size of HTML a result of the creation of a separate file
folder? When I add up the size of the folder and the size of HTML, it is
actually much larger than MHTML. I like the fact that, with HTML's separate
folder, I can manipulate the images (JPEG, GIF etc.), sound files, and even
the master. Can you give me more scenarios as to when I want to save as
MHTML and when HTML?

(3) Is it true that without password protection and as long as others can
view the show, they can always manipulate my presentation regardless of what
file type I save it to and send it as an e-mail attachment?

Appreciate advice.

Most of them are self-evident. JPG is JPG, etc.

PowerPoint 97-2003 & 95 Presentation is a dual-format version that either PPT
97 onward OR PPT95 can open. No point in using it unless you can find somebody
who still uses PPT 95. If so, try not to move them. They'll probably be dusty
and brittle after all this time. ;-)

Yes. The one HTML file you see is just a kind of introductory slide/pointer.
The rest of the presentation is in the folder of the same name. The one HTML
file by itself won't be useful.

The MHTML combines all the "support" files in the folder into one big file.
Convenient but it may not be supported by all browsers.

If it's a format that opens back into PPT as a presentation, yes.

If you save as a series of JPGs, then they can edit each JPG in a picture
editor but changing the text that way would be VERY tedious.
 
I think this is a good web site http://www.webopedia.com to help me
understand the "save as" file types under PPT.

Today I learned that PPT uses WMF to hold both vector and bit-mapped images.
I also learned this:

Can someone confirm that the info on this website is reliable and uptodate
please.

"The information that is discarded in the compression is information that the human
eye cannot detect."

...

"JPG does not work well on line drawings, lettering or simple graphics because there
is not a lot of the image that can be thrown out in the lossy process, so the image
loses clarity and sharpness."

But in a way undetectable to the human eye? ;-)

A little self-contradiction there. What they probably meant to say was that IN
MODERATION and used on photographic images, the results of JPG compression aren't
detectable to the human eye.

Does that mean that if there are flies in the audience, you need to worry about it?
I don't know.

A small complaint. The rest of the information seems correct, except that I think
that developers can now write apps that create GIFs w/o paying fees to Unisys and
I'm fairly sure that all modern browsers now support PNG.
