# Installation

Copy the folder "UnitySweeper/Editor" of this project into the "plugins" folder, under the assets folder of your Unity project.

The path should look like this: "Assets/Plugins/UnitySweeper/Editor".

# Unity Sweeper

This plugin helps you sweep up your project - it detects unused files, removes them from the project, and creates a backup of the removed assets exported as a unity package.

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

![Window menu choices](https://raw.githubusercontent.com/NotionTheory/unity-sweeper/main/Images/01.png)

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

> [!NOTE]
> If you choose _Unused by Game_, it will also remove this plugin itself by default.<br>
> You can click the button _Exclude plugins_ in the next window to prevent this behaviour.

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`.

Enjoy!
