    Output

    Explicit local files only. Originals stay unchanged. Identical groups use SHA256 and byte verification; no deletion. Up to1000 files,64MiB/file,256MiB total.

    What should I check in the output?

    Keep all the parts together with the indexed manifest. Joining checks the order, names, lengths, the SHA256 of each part and the overall hash. Compare the joined file’s bytes or hash with the original. This splits raw bytes and is not archive extraction.
