"Where can I find my Bedrock world files?" is missing procedures for backing up / transferring worlds on iOS / iPadOS (and Android), despite them having their file managers pre-installed as a new device. (Although I don't have an Android device, I can list a procedure on iOS / iPadOS.)

Here's my way to access Minecraft Bedrock World files on iOS / iPadOS via Files app:

1. On the home screen, search for Files (if installed) and open it
2. Click / tap "My iPhone" / "My iPad"
3. Click / tap "Minecraft"
4. Click / tap "games"
5. Click / tap "com.mojang"
6. Here, you can backup / transfer not just worlds (MinecraftWorlds), but also imported contents that can't be restored through Minecraft Marketplace ("behavior_packs" for imported behavior packs, "resource_packs" for imported resource packs, another two in same names but with "development_" before are obviously for development, "skin_packs" for imported skin packs and "world_templates" for imported world templates)
