I’m not sure where to post this but, is their not an option to remove content that isn’t being used, I have over thirty asset folders in my content section and only 10% of some of the content in these folders is being used, it would be really easy to remove unwanted textures models and blueprints If I could just right click the folder and delete all content not already being used is their an option for that?
if you are pack the game/project then it will avoid the unused assets and only pack the assets referenced by the project
Yeah I get packing the game will only use the assets being used, its just loading the project takes ages because of the amount of content in the project, but migrating the main map to a different project is the easiest thing to do I think read here Delete all unused assets - Feedback for Unreal Engine team - Unreal Engine Forums
Also their are many apps you can buy from the market place to help with sorting things out but they don’t work in 4.20
