When you import Asset StoreA growing library of free and commercial assets created by Unity and members of the community. Offers a wide variety of assets, from textures, models and animations to whole project examples, tutorials and Editor extensions. More info
See in Glossary assets, the Unity Package Manager places them in the
Assets directory in your project.
You can manually remove assets from a project if you know the assets aren’t in use. You might consider this action to unclutter your project directory or to free up space on your local hard drive.
Warning: Make sure your project isn’t using any of the assets you remove. Unlike installed packages, the Package Manager doesn’t track imported packages, so it can’t detect when you remove dependent assets.
Make sure you understand these important notes before you begin:
Use this procedure to remove assets only if you added them to the current project by importing them by following the Importing an Asset Store package procedure or by importing a custom package. Don’t use this procedure to attempt to remove packages that you installed from a registry. For information about removing packages that you installed from a registry, see Removing an installed package from a project.
This procedure removes assets from the current project. It doesn’t remove the same assets that might exist in other projects. It also doesn’t remove the package from the Asset Store cache. To completely remove an Asset Store package and its assets from your computer, you must remove them from multiple locations:
To remove imported assets from your project:
Open your project.
Open the Package Manager window.
Open the Packages menu and select the My Assets context.
Select the package you want to remove from your project and take note of the package name (A) and the publisher name (B). These names might help you identify the asset directory in a later step.
Locate the subdirectory for the package you identified in the Package Manager window in a previous step.
Explore the directory structure that the publisher created (C), confirm it’s the correct package, and identify the assets you want to delete (D). Note: Unity doesn’t impose directory names or structures on publishers, so their assets might not be in an easily identifiable directory. The directory structure might be simple or complex.
Select the asset or assets you want to delete. Your selection can be a single asset, multiple assets, all assets in a subdirectory, or more.
Right-click the selected items, and select Delete.
Important: ScenesA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary that depend on deleted assets aren’t reported as errors in the Console windowA Unity Editor window that shows errors, warnings and other messages generated by Unity, or your own scripts. More info
See in Glossary. If you suspect the removal caused issues, import the package again. See Importing an Asset Store package.
