Zipped a file but the zipped file wasn't much smaller than orginal file. eg.
16.7 mb
zipped was 16.2mb. How do I make it zip smaller. xp home with office 2003.

You might not be able to. Just because file compression exists does not
mean all files can be made a certain percentage smaller.

There are many files that just cannot be compressed much. They are already
saved efficiently. In those cases - you can compress all you want, but you
may never get it more than a few percentage points smaller. However some
files contain LOTS of empty data and thus - can be compressed 75% or more of
their original size.

Hi, Not a great computer user. It was a powerpoint doc that was too large to
send by email, so I tried to make it smaller to be able to send it.
Was using the built-in zipper.

There's the story about the guy who took a 5Mb file, zipped it, then zipped
the result, and so on through enough generations to end up with a file only
three bytes long!

He became so distraught that the file couldn't be made smaller, that he put
motor oil on his corn flakes.

Perhaps you inserted too many large pictures? If that is the case, use
Edit Pictures in Picture Manager to "compress" copies of the pictures to
"document size", and use those instead. Warning, "compress" is a "lossy
compression" so DON'T compress your originals. "Zip" is "lossless"
compression and that is likely the reason you don't get much compression
as the pictures are already compressed as "jpg" files.
