about

nx_dr_tree.nx -- CAP-DR-TREE: recursive + STREAMING archive of a whole directory tree to a separate drive (for large content: galx, reference, search-data, wiki). Walks src (getdents64), mirrors the structure under dest (mkdir), streams each file in 1 MiB chunks (NO size cap -> handles multi-GB media) and size-verifies the copy. Additive-safe (reads src, writes only dest). Composes nx_lsdir's getdents primitives. argv: [1]=src-dir [2]=dest-dir. license_tier: ORIGINAL
