api.FileSystemFileHandle.move available in Chrome

[jozefchutka]

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

FileSystemHandle API: move is reported as not supported for Chrome, however it exists and works in runtime.

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet)

What did you expect to see?

Expected to see it is supported

Did you test this? If so, how?

FileSystemFileHandle.prototype.move
// -- > ƒ move() { [native code] }

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

whatwg/fs#10

Do you have anything more you want to share?

It somehow went off radar of chromium devs even though it was delivered in past. It is hard to find any traces:

• I can reproduce that the FileSystemHandle prototype exposes the move method in Chrome 136.
• Chrome 95 added FileSystemHandle::move() and FileSystemHandle::rename(): chromium/chromium@89be8a8
• It looks like they're behind the FileSystemAccessAPIExperimental runtime flag though (--enable-blink-features=FileSystemAccessAPIExperimental): https://github.com/chromium/chromium/blob/fdbfa4b5f674400c93cad38a4a27b1a62a1b8dce/third_party/blink/renderer/modules/file_system_access/file_system_handle.idl#L35-L50
• Moving directories appears to not be supported yet, see Chromium bug 40198035, which references several related changes, and comment 15 mentions:

  Moving files is currently only supported within the OPFS, for which
  permission requests are automatically granted.

Overall, it is not obvious to me what's really supported.

@jozefchutka Could you try what works on https://file-system-terminal.glitch.me/ without enabling the experimental features flags? It might be that the method is exposed, but doesn't work.

move works for me in chrome 136 with both FS and OPFS using glitch.me demo

I am using the following ts type in my code which works with chrome, safari and firefox

declare global {
	interface FileSystemFileHandle {
		readonly move:(directory:FileSystemDirectoryHandle, newName:string) => Promise<void>;
	}
}
