I have a question about the mesh management in Blender.
In this question 55 woo shares a file. If I take a look into the Outliner I'll find 3 objects. But if I select an object and go into the Object Data panel, in the top dropdown menu I can find a lot of other meshes, even though they are not marked with the F of Fake User:
I can also find these meshes in the Outliner if I choose to display the Orphan Data. It will display a series of greyed objects that don't exist anymore, and if I unfold one of them it will show its mesh, which is supposed to have 1 user, but it doesn't as the object is not here:
So of course I can purge these meshes with the Purge button of the Outliner, or File > Clean Up > Unused Data-Blocks. But why are these meshes even here when they are not used and are not even marked as fake users, why are they not managed like any other data like materials or actions, which disappear when the file is closed, and how did this happen?
I can't reproduce the problem from scratch, if I create an object, delete it, close and reopen the file, the mesh of this object isn't available anymore.
Thanks in advance.
