New Project folder

1. File> New Project> Setup default for… 3D> setup a path and a name for this project (example D:\Unity\Space-Shooter-001), IMPORTANT: you have to choose a empty folder!

Inside the folder Unity has created the folders:
– Assets
– Library
– ProjectSettings
– Temp

You can add a folder ‘Package’ and copy your .unitypackage
This in the better way to organize your folders in my opinion.
WARNING: If you import an .unitypackage from a removable flash drive you will get an error

Import Package .unitypackage

2. Assets> RMB> Import Package> Custom Package> select the package ‘name.unitypackage’
NOTICE: .unitypackage is a sort of .zip with all resource you need inside. The contain usually is meshes, textures, materials, physic, music, scripts and so on…

3. The importing windows appears, now you need to choose what you need> ‘Import’

4. Assets> differet folders appears, for example Audio – Materials – Models – Prefabs – Textures etc…

5. Inside the folder ‘Assets’ Unity has copied all content of .unitypackage and the decompress content is organized in different folders:
– Audio
– Materials
– Models
– Prefabs
– Texture
– etc…

– Library
– ProjectSettings
– Temp

Export Package .unitypackage

1. Open a Project

2. Assets> Export Package…> check ‘Include Dependency’, ‘Export’
