Has anyone decoded (i.e., reverse engineered) the format of the Quicken database? Is it published somewhere? I'm impressed that they have a design that has remained secret since the late 1980s even though I'm sure many of their programming staff have come and gone.
Quicken database format?

The schema of the database has changed over the years.
True, and that's another impressive feature of the design. Quicken for any year can read all prior databases. I imagine something like a random number seed that changes each year.
Just put a version number in the data file. That's easy.
What is impressive is not how it is done, but that Intuit decided to do it. Intuit is not the most customer-oriented company out there.
I don't think that's true. I have many old Q disks that my current version, Q2009, cannot comprehend.
Many years, when I upgraded, the former version's database had to be converted. If one "spread" too far - if, for example, one tried to leap from Q2000 to Q2007 - the program couldn't manage it, and you had to find an intermediate version such as Q2004 to "pre-convert" the ancient database.
But maybe I'm quibbling. Maybe all you meant to say that users of older versions were never orphaned, because Q(n) could always upconvert the data from Q(n-1). But if that's all you meant, that's faint praise; what program ever did such a thing?
