How do I exclude Unity's assets in results from from AssetDatabase.FindAssets?

I wrote an editor script tool to find all textures in the project, which are not power of two sized, and not in an Atlas…
It mostly works… The problem is, unity also returns a whole bunch of other textures, that if you search for them by the name that unity gives in the project window … they are not in the project hierarchy anywhere… defeating the effectiveness of the tool.
I am guessing these ‘noise’ textures are unity standard assets, Editor icons, possibly textures in libraries or plugins etc… I just want my own project’s textures. So how would I go about doing that?
The path for all those assets is not a path, it’s just a guid, so I cant filter by asset path either.

unity 2019.2.7

any ideas appreciated. Thanks in advance.

I’ll answer my own question…
load the asset by guid, then get the actual path…
string assetPath = AssetDatabase.GetAssetPath( asset );
then filter on the path string.

I am hoping that there is a filer option for this… Filtering yourself afterwards seems very inefficient.
