# file

The app entity describes a file.

```
var file: some AssistantSchemas.Entity { get }
```

## Overview

Use Swift macros that generate additional properties and add protocol conformance
for your app entity implementation. The following example shows an app entity that conforms to the `.files.file` schema:

```swift
@AppEntity(schema: .files.file)
struct ExampleFileEntity: FileEntity {
    var displayRepresentation: AppIntents.DisplayRepresentation { "Example File" }

    static var supportedContentTypes = [UTType.image]

    var id: FileEntityIdentifier

    @Property
    var creationDate: Date?

    @Property
    var fileModificationDate: Date?

    struct Query: EntityStringQuery {
        func entities(for identifiers: [ExampleFileEntity.ID]) async throws -> [ExampleFileEntity] { [] }
        func entities(matching string: String) async throws -> [ExampleFileEntity] { [] }
    }
}
```
