Category: Offline / Storage
Type: No developer-visible change
Status: Enabled by default (Chrome 109)
Intent stage: Shipped

Summary

Enable the Origin Private File System (OPFS) part of File System Access API on Android. This includes all of the File System Access API surface, minus show*Picker() methods and Drag-and-Drop API integration. With FSA API on OPFS, a site can access its per-origin, private file system and are able to perform file operations via `FileSystemSyncAccessHandle` with improved performance. The original API, including both OPFS and non-OPFS, was shipped in M86 for desktop, and the extension with SyncAccessHandle was shipped in M102. https://chromestatus.com/feature/6284708426022912 https://chromestatus.com/feature/5702777582911488

Motivation

By enabling Origin Private File System API on Android, it expands cross-platform compatibility. On Android Chrome and Webview, sites can utilize per-origin, private file system, along with performant access to files via FileSystemSyncAccessHandle.
