# Excluding from coverage or duplication

You can exclude specific files from your project’s code coverage analysis or duplication check analysis (detection of identical lines of code).

{% hint style="info" %}
As the admin an Enterprise plan organization, you can perform this setting as the default setting for all projects of your organization. See [exclude-from-coverage-duplication](https://docs.sonarsource.com/sonarqube-cloud/administering-sonarcloud/managing-organization/setting-config-at-org-level/adjusting-analysis-scope/exclude-from-coverage-duplication "mention").
{% endhint %}

## Excluding specific files from the code coverage analysis <a href="#from-coverage" id="from-coverage"></a>

You can perform the setup in SonarQube UI (this requires that you have the project’s Administer permission) or on the CI/CD host. A parameter set on the CI/CD host has precedence over any UI setting of the same parameter.

1. Retrieve your project. See [retrieving-projects](https://docs.sonarsource.com/sonarqube-cloud/managing-your-projects/retrieving-projects "mention") for more details.
2. Go to **Administration** > **General Settings** > **Analysis scope**.
3. In **Code coverage** > **Coverage Exclusions**, enter and save a path-matching pattern to define files to be excluded from the code coverage analysis. See [defining-matching-patterns](https://docs.sonarsource.com/sonarqube-cloud/appendices/defining-matching-patterns "mention") for details.
