Are you on Mac or Windows?
I'm on Windows 7 I think
Package your indesign file (File>Package)
It creates a new folder with all your files inside it.
Select the newly created folder.
Right click - Send To>Compressed Zip
Once you package a file, it's wise to use this packaged folder from now.
Therefore archive your old files so you don't mix them up.
Thanks for jumping in, Eugene.
Alas, I only have a few hours a weekend to jump in. New job takes up most of my week!
Thanks so much for your assistance!!!! That worked!
