# FileSource

A search source that retrieves indexed metadata from files and directories visible to Spotlight.

## Declaration

```swift
struct FileSource
```

## Mentioned in

Making your indexed content available to Foundation Models

## Overview

Overview Use this type to search the metadata of your app’s custom file types. Configure the source with one or more directories for the tool to search. During a query, the Spotlight considers only the previously indexed files in those directories. When it finds a match, the tool delivers the item and any attributes you specify in the fetchAttributes property to the model for consideration. For more information about indexing your app’s files, see CSImportExtension.
