Delete all unused assets

It is already inside UE4 Editor, although it is not exactly one button ‘cleanup my assets, please’

1. Create a new project (this is supposed to be the clean project with all needed asset)
2. Inside UE4 Editor, working with existing project (which has many unneeded asset), select a level and then right click, Asset Action -> Migrate.
3. Migrate to the new project just created (select the Content folder).
4. The migration will copy all referenced asset to the new project
5. Repeat for all levels.

It seems like this solution is the best so far ( tried the command suggested and it deleted about 30mb while this one deleted more than 1gb )

I didn’t test it thoroughly but it seems like it is working fine.

Just need to keep in mind to make the new project with the exact same name as the old one in order to have Cpp code work ( my project is using blueprints that inherits from Cpp and from plugin’s Cpp )

So what I did basically is:

1.copy the plugins, source and config folders to the new project.
2.Migrate the levels from the old projects to the new one’s content.
3.Generate project files and build in visual studio

And that’s it.
