Tom, I find that creating and saving reports within FTM significantly increases the size of my file. If I later delete those reports, compacting the file can reduce its size by up to 20%. I compact regularly and can see how someone who does not could easily get to 50% or more.

I was surprised to see that the fle was reduced by 50.5%  That's pretty scary. How could that be?
