Cross-browser JS Filesystem API

Question

I'm aware of the JS Filesystem API for reading/writing files in the Chrome sandbox.

But I cannot find a W3C standard that does the same, is there a cross-browser way to read/write files on major browsers?

Thanks

No, because that would be a major security hole. You wouldn't want a website starting to write files into your filesystem. So vendor specific solutions exist, like the one you mentioned. IE uses ActiveX. But there is no general standard. — Mouser

I meant reading/writing in a sandbox, not on the local filesystem of the user. — Mathias Maes

The W3C File System API standard has been discontinued, so probably not. — Pointy

The only cross-plattform solution to save data persistently I'm aware of is local / web storage, specified here : w3.org/TR/webstorage. — Tacticus

It is recommended to use the Indexed Database API (large data, and a-synchronous) as the File System API is discontinued. Web Storage API can also work but it's synchronous and for small data.

Can the Indexed Database API provide similar persistence guarantees? (I.e.: data will not be cleared without explicit action by the user).

@Alec yes they are persistent.
