Unity Package Files (*.unitypackage)


Asset Manager provides handling of assets from both the Asset Store as well as downloaded assets. Once you download an asset from the Asset Store it will automatically show up in your package list the next time you open Asset Manager or if you hit the refresh button. You can also add filesystem search paths for your assets from other sources like the Synty Store or CGTrader. The hierarchy of the assets is controlled by the subdirectories under each search path.

Adding Search Paths

If you have an asset collection beyond the Asset Store you’ll want to add search paths to the Package tab’s settings.

  1. Open the package tab and click on the settings cog.
  2. In Settings Click on the Add button next to “Additional package paths”
  3. In the new field click Browse and find the directory you stored your *.unitypackage files in. Ideally these should be stored in directories under the search path. Each directory in that path will be grouped in with the package hierarchy. This hierarchy matches the Category hierarchy provided on the asset store. For example a file stored in directory structure [TargetDir]/3D Models/Characters/Animals/ZOMBIE Collection.unitypackage will be reflected in the Package hirearchy.


For the most part search is pretty basic. The search bar will search through package names. There are two additional search methods that may be useful: author search and prefab search.

To do an author search type “a:” before your search term. This will search the author field instead of the package name field.

The prefab search feature searches through the files in your unity packages and provides matches to packages that contain prefab files matching your search term. If there is a thumbnail for the prefab it will be shown in the search.
Example: “p:dragon” results in a list of turtle prefabs. This is a great way to find lost prefabs in your collection.

Installing Packages

There are two ways to install packages: Quick Import and Interactive Import. When you’re ready to import packages find the packages you want to import and click the checkbox next to them. Asset Manager provides a means to import multiple packages at once. If you use the Quick Import button you will import all of the selected assets without interaction. This is a great way to get a new project setup.

Tracking Installed Packages

Asset Manager tracks any package that it imports. You can view your installed packages under the Installed item in the package hierarchy. You can also view your installed packages in the Credits tab.

Audio Workflow

Audio Management in a Nutshell

Asset Manager provides a convenient tool for finding and importing audio files from your filesystem into your projects. This is a great way to manage audio assets purchased and downloaded from sites like Humble Bundle.

The Process

The general recommended workflow is to store and organize audio in a private or team repository like Dropbox. I generally organize all of my audio assets in a directory in Dropbox that can be used on whatever device I am using Unity from.

  1. Create a Dropbox directory to organize the assets
  2. Download audio assets and store them in the directory you created.
  3. Add the Dropbox directory to the search paths in Asset Manager’s Audio tab settings page
  4. Hit the save button
  5. Refresh assets

Once you have your audio collection added to the Audio tab’s search path you can search for audio, preview it, and import it into your project.


On Windows you will only be able to playback some audio formats in the tool (a fix for this is planned).
