You could make sure that Fast Saves is turned off and Save As to another
name and delete all the other slides. Any other method is unlikely to work
because a slide doesn't necessarily have a size in the way you might think.
For example, a sound that is embedded in the presentation could be shared
across several slides. If the sound is, say, 1 MB, and it is used in 10
slides, is one of those slides 1+ MB or is it 100+ K (1/10 of 1 MB)?
