Imported world is much larger than the same backup world

Help
1

Hello,

I imported my local Foundry VTT world through The Forge Import Wizard and used the overwrite option for the existing world.

The imported world “Forgotten Realms” is now shown as 76.40 MB. A backup copy of the same world is only 62.96 MB.

I also noticed that cloning an imported world can reduce its reported size by approximately 8–10 MB without any content changes.

Could you please check what database or stored data is causing this large difference, and whether the import process leaves duplicate, obsolete, or un-compacted data behind?

Environment:
Foundry VTT 13.351
D&D5e 5.3.3
World ID: dnd
Forge region: EU

I have attached a screenshot showing the different world sizes.

Thank you.

Hello,
Thank you for reaching out for help here. This is fairly common upon importing a world, and is usually the result of database operations. It is expected behavior, and the world size will eventually shrink.
