Design docs https://web.dev/file-system-access/#accessing-the-origin-private-file-system

Summary Enable the Origin Private File System (OPFS) part of File System Access API on Android. This includes all of the File System Access (FSA) 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.

TAG review This API has been shipped on Windows, Mac, Linux and Chrome OS, with two parts. The API to be shipped on Android is the same, thus relying on the previously completed TAG reviews:

• File System Access API: https://github.com/w3ctag/design-reviews/issues/390

• Access Handle: https://github.com/w3ctag/design-reviews/issues/664

TAG review status Completed

Risks

Interoperability and Compatibility

Gecko: In development (https://bugzilla.mozilla.org/show_bug.cgi?id=1748667)

WebKit: In development (https://bugs.webkit.org/show_bug.cgi?id=231706)

Web developers: Strongly positive (https://crbug.com/1011535)

Other signals:

WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?

No, it does not change any existing APIs but to enable a new one.

Debuggability Basic tooling: Autocomplete works as described in "New WebIDL/DOM interfaces and attributes".

Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes

This feature was initially launched on desktop, and this proposal includes Android Chrome and Android WebView.

Is this feature fully tested by web-platform-tests? No

Web Platform Tests are not available on Android.

Flag name FileSystemAccessOriginPrivate

Requires code in //chrome? False

Mike Taylor Sep 22, 2022, 5:33 AM (9 days ago) LGTM2 (The answer should probably be yes here, I think.) Out of curiosity, do we have (manual?) tests that cover the DnD functionality that this intent does not

Marijn Kruisselbrink Sep 22, 2022, 11:00 AM (9 days ago) There are browser tests for the DnD functionality. Chrome's web platform test infrastructure bypasses so much of chrome's drag&drop implementation that even if

'Daseul Lee' via blink-dev Sep 23, 2022, 10:12 AM (8 days ago) Thanks for the review! WPT is no longer available to run on Android. It looks like there is some coverage for Drag-and-Drop, but as Marijn mentioned, it doesn't
