How to COMPARE versions of Visio 2003 DRAWING files?

[Alan Jones]

I get a Visio Drawing file (.vsd) periodically.
Is there anyway to automatically tell what has been changed by comparing it
to an older version?
Is there a compare funtion for drawing files like there is for organization
charts?
I am interested in a solution either within Visio or 3rd party tools.

Manually hunting for the changes is a bear.

I guess something that might be considered is to save both as xml and then
use a utility that looks at text.

No I take it you are saying NO Visio does not provide a way nor is there a
3rd party software that can do it in .vsd format. Its a shame! I know many
people who would buy such a program.

It's one thing to compare two shapes, another thing totally to
compare, say, the contents of two pages. Even the relatively simple
operation of deleting one shape and adding another will put the shapes
in a different order in the shapes list.
