This is a March 2024 summary and collection of links to the state of protocols and implementations around WNFS, an encrypted file system that can be used with IPFS, and CAR Mirror, efficient transfer and synching of content addressed data.
WNFS
WNFS is the “Web Native File System”.
Working Group / protocol repository: https://github.com/wnfs-wg
rs-wnfs implementation https://github.com/wnfs-wg/rs-wnfs
CAR Mirror
“rsync for DAGs”
rs-car-mirror, streaming, and HTTP2
Loom by @matheus23. Current state of implementation of rs-car-mirror, both in browser via Wasm, and everywhere else with Rust binary
Repo with code https://github.com/fission-codes/rs-car-mirror
CAR Mirror is used to transfer IPLD from one computer to another over the internet over various transports, but most notably HTTP(s). It tries to do so with deduplication and minimal communcation round-trips.
CAR Mirror Reflections
From Belgium, go-CAR Mirror plugged into Kubo:

Previously
We built a visual interface into IPFS powered by the JS version of WNFS in browser.
See Fission Drive https://drive.fission.codes/ – this is a little stale, but can show you lots of file interactions in browser.
And ODD SDK demos https://odd.dev, which bundled WNFS and has a very basic drag and drop interface, including for private files.
