# Introducing Unity Sweeper - a tool to remove unused assets from your Unity project

We’re often the recipients of large Unity projects overdue for optimization or a spring cleaning. Commonly, these inherited projects are bloated with unused assets and no matter how much time we spent on cleanup, unused assets always sneaked through.

We’ve released an open-source tool called “Unity Sweeper” which detects unused files, removes them from your project, and creates a backup of the removed assets exported as a Unity package.

You can find the github repository here: [https://github.com/notiontheory/unity-sweeper](https://github.com/NotionTheory/unity-sweeper)

Using the tool is really simple. You can initiate deleting unused files through the `Window` menu.

Options are:

- _Only resource_ \- Will sweep everything except scripts
- _Unused by Editor_ \- Will sweep everything used by game or editor, including scripts
- _Unused by Game_ \- Will sweep everything used by game, including scripts
- _Clear cache_ \- Deletes cache files

If you choose any of first three options, Unity Sweeper will run a search through your project, after which it will show a screen like this:

...from where you can review the unused assets found, uncheck assets which you want to keep in your project, and select the assets you want to exclude from your project. Unity Sweeper will also remove empty directories.

Clicking the _Exclude from Project_ button will create a Unity Package with current the datetime and export the package to the location of `PROJECT_ROOT/BackupUnusedAssets`.

Happy unused asset hunting!
