[enhancement] local file support?

[kallisti5]

Any interest in local file support for this one?

I was looking at ipfs/kubo#7586 and this tool might be a good solution for that use case?

Large (size + file count) local filesystem directory, few changing files.

1. Calculate CID of each file in local filesystem, ask IPFS node if it already has the file
2. Doesn't have? ipfs add, does have? Continue
3. Generate directory CID with correct filenames + CID's
