How do I know the progress of getting a large file

files.get or files.cat . How do I know the progress of getting a large file(video or image). The optional parameters described in the document are offset and length.

This is not currently spec'd and is not implemented in js-ipfs or go-ipfs implementations. @diasdavid do you know if this is planned/possible?

Note that if you catReadableStream or catPullStream you'll know how much you have as you get streamed chunks, but you'll not know the total file size.

You can probably use object.stat to get the total size beforehand but in the future hopefully files.stat will support both MFS as well as IPFS path and you'll be able to use that.

Nothing planned but this seems like good feedback for https://github.com/ipfs/interface-ipfs-core/issues/284. Thanks for bringing it up, @xuruijing
