The best way to reduce the size of any kind of file is to be judicious &
selective about what you put into it in the first place
If you load a
file up with 2MB pictures where 700K images would suffice, you'll wind up
with a file significantly larger than it needs to be. Trying to make the
file smaller after the fact may not be effective - perhaps impossible.
It's hard to suggest how to reduce the size of your file without having any
idea what it is that's causing its size in the first place... And you
haven't even indicated what the file size is. There are folks here willing
to help, but you need to give them something to work with. One-liner
postings with no detailed information is a waste of your time & most of
those who volunteer their time & effort here aren't going to arbitrarily
speculate in reply to what appear to be 'test' or 'homework' questions.
