# FileSystem API This directory contains part of the browser side implementation of various filesystem related APIs, as well as interfaces to treat various types of native and non-native filesystems mostly the same without having to worry about the underlying implementation. ## Related directories [`//content/browser/fileapi/`](../../../content/browser/fileapi) contains the rest of the browser side implementation, while [`blink/renderer/modules/filesystem`](../../../third_party/blink/renderer/modules/filesystem) contains the renderer side implementation and [`blink/public/mojom/filesystem`](../../../third_party/blink/public/mojom/filesystem) contains the mojom interfaces for these APIs.
