Project Size keeps growing?

I’ve noticed that my project size keeps expanding at a rate that seems too large. Even when all I do for a few hours is a couple of C++ classes that use meshes already present within the content folders of the project, the project grows by 500mb, or more, to the point where adding the 15 or so classes that I have over the last week has added multiple Gb to the project size, and all I have to do is build the project for this size to increase.

Is there a cache somewhere with redundant data or another method of cleaning up the project?

There is the database file C++ uses. It gets big sometimes. Should be in the project folder with ProjectName.VC
