## listAll() function

List all items (files) and prefixes (folders) under this storage reference.

This is a helper method for calling list() repeatedly until there are no more results. The default pagination size is 1000.

Note: The results may not be consistent if objects are changed while this operation is running.

Warning: listAll may potentially consume too many resources if there are too many results.

<b>Signature:</b>

```typescript
export declare function listAll(ref: StorageReference): Promise<ListResult>;
```

A Promise that resolves with all the items and prefixes under the current storage reference. `prefixes` contains references to sub-directories and `items` contains references to objects in this folder. `nextPageToken` is never returned.
