Opening blender as a folder

Hi, when I try to “Append” a .blend file, I see each folder that makes up the file, is it possible to do that directly from windows? Because when I am appending I can’t modify anything, and I’d like to delete some of these folders since they are useless for exporting into unity

Don’t worry about it. When you export you will only export the relevant data.

What exporter are you using to get your models into Unity?

FBX exporter, for some reason a “.fbm” folder is being created when I import it into unity
