Downloading Multiple Large Files Fails

[hacdias]

Describe the bug

Downloading large files fails due to the usage of ipfs object add-link. See https://github.com/ipfs/go-ipfs/issues/7421.

To Reproduce Steps to reproduce the behavior:

1. Go to Files
2. Click on multiple large files
3. Click on 'Download'
4. See error

Expected behavior Download the files.

Additional context

See https://github.com/ipfs/go-ipfs/issues/7421. We should move to the MFS API, perhaps through some kind of temporary file on the MFS?

Perhaps something such as /temp/Download {timestamp}. cc @lidel

@hacdias yes, for HAMT our only option is MFS at the moment. My thinking:

• create directory named /zzzz_{timestamp} (so it is at the end of file list – minimizes the risk of UI jitter in case React refreshed file list that exact moment ;))
• cp references to files there
• copy CID of the zzzz directory (ipfs files stat)
• start download of the archive with CID contents
• remove the zzzz directory (safe to do asynchronously after the download already started, even if GC is enabled, the root block server its purpose)
