What is the .DeveloperState file and how should it be managed with git?

Hi everyone,

In the project folder of the model I'm working with, there is a binary file called Main.DeveloperState. I have looked through the documentation but I can find no information on what this file is and does exactly, except that is somehow related to pivot tables.

We use and run the model through AIMMS itself, using pages. The DeveloperState file is modified occasionally, but again: it not clear to me what causes these modifications, or what they represent. We work with multiple developers and use git for version control. Because the file is binary, it is not clear how it should be merged (if at all).

My questions:

1. What is the purpose of this file?
2. What happens if you delete the file?
3. How to best treat it in git? Can it be ignored?

Thanks in advance!
