Short description of error
assets of non active scenes arent purged of elements with zero users after saving and re-opening

Exact steps for others to reproduce the error
open the attached file, open the 3 scenes one at a time and delete the mesh from each. Change the outliner to blend file mode so you can see how many materials etc there are in the current scene. Save the file, re-open the file. Open each of the scenes and notice that only the materials etc of the scene that was active during saving/re-opening were removed from the blend file.

Hi, thanks for the report.

I could not reproduce this on 2.81 or my local master. Every time I tried it worked as designed. All meshes (3 of them) would be deleted from the file once I reopened it. If I repeat the process of saving and opening two more times then the materials and then textures would also be deleted. Note you can see what should be deleted if you go to outliner and set display mode to Orphan Data.

ah ok, I didn't realise you had to save and re-open the file 3 times for unused assets to be purged. I'll just write a bit of python to automatically do it without saving and re-opening, is there an inbuilt function already, or do I need to loop through each data type one by one?

If you select the display mode of the outliner to Orphan Data then a Purge button shows up that you can click to remove things that have 0 users. The python code for the purge operator is "bpy.ops.outliner.orphans_purge()"

Closing for now, reopen if you can find an error.
