### Returns

- `type DeletedFile struct{…}`

  - `ID string`

    ID of the deleted file.

  - `Type DeletedFileType`

    Deleted object type.

    For file deletion, this is always `"file_deleted"`.

    - `const DeletedFileTypeFileDeleted DeletedFileType = "file_deleted"`

### Example

```go
package main

import (
  "context"
  "fmt"

  "github.com/anthropics/anthropic-sdk-go"
  "github.com/anthropics/anthropic-sdk-go/option"
)

func main() {
  client := anthropic.NewClient(
    option.WithAPIKey("my-anthropic-api-key"),
  )
  deletedFile, err := client.Beta.Files.Delete(
    context.TODO(),
    "file_id",
    anthropic.BetaFileDeleteParams{

    },
  )
  if err != nil {
    panic(err.Error())
  }
  fmt.Printf("%+v\n", deletedFile.ID)
}
```

#### Response

```json
{
  "id": "file_011CNha8iCJcU1wXNR6q4V8w",
