Hello. I use UE5.0.3 and I can’t understand at the moment:
Should I delete all unused objects and texturies from Content Browser before Packaging a Project?
My game is very small but its weight is 12 GB, I start to believe that it is because of all unused libraries in the project.
Please let me know how should I proceed, deleting or not deleting all unused libraries from the Content Browser tab?
Thanks.

Hi,
Packaging the project should not include any asset that are not referenced by the maps, so maybe you have a test map or something that is referencing some assets that you don’t want in the final build. In the project settings find “List of maps to include in a packaged build” and include only maps that you want. Also disable “Cook everything in the project”.
you can
but it isn’t completely necessary
I have several projects that have more than 10g of working assets
but once I cook them down with only specific maps
the end product is less than half a gig.
a good way to clean up a proj is to select just the levels you actually are going to pkg, and migrate the levels to a blank proj
any assets not in those levels won’t be migrated
Thank you Polysiens for your answer!
Thank you Christuusgnosis for your answer!
At the same time - I would be very thankful if you explain me how to migrate a level to a blank projects in two words. 
I am only about 5 days in UE5. Never did that before. 
right click the level and asset actions migrate to the blank
Thank you!
