## I want to reduce the size of the cache for an app
<a name="reduce-cache-size"></a>

If you are using the cache, you might be caching intermediate files that aren't cleaned up between builds. Caching these infrequently used files will increase the size of your cache. To prevent this, you can exclude specific folders from being cached by using the `!` directive in the `cache` section of your app's build specification.

The following build settings example demonstrates how to use the `!` directive to specify a folder that you don't want to cache.

```
cache:
  paths:
    - node_modules/**/*
    - "!node_modules/path/not/to/cache"
```

When you cache the `node_modules` folder, `node_modules/.cache` is omitted by default.

For a full example of the build specification settings for an Amplify app, see [Build specification YAML syntax reference](yml-specification-syntax.md#build-yaml-syntax)

If you want to disable reading from the cache for an app, remove the cache section from your app's build specification.
