    "incantation": "When copying files or folders between Hub repositories, use `copy_files` with `hf://` source and destination URIs; use `hf buckets cp` for CLI repo-to-repo file copies. For direct `CommitOperationCopy` cross-repository sources, set `src_repo_id` and `src_repo_type` (required when `src_repo_id` is set).",
    "examples": [
      "from huggingface_hub import copy_files\n\ncopy_files(\n    \"hf://datasets/<owner>/<source-repo>/data/\",\n    \"hf://datasets/<owner>/<target-repo>/data/\",\n)",

      "Version: v1.17.0",

      "destination URI / `path_in_repo` (required): Destination URI for `copy_files`; destination repository path for `CommitOperationCopy`.",
      "`src_repo_id`: Source repository ID; defaults to the destination repository. If set, `src_repo_type` is required.",
      "`src_repo_type`: Source repository type: `model`, `dataset`, or `space`; required when `src_repo_id` is set.",
      "`src_revision`: Revision to copy the source file from.",
      "CLI `SRC` and `DST` (required): The source and destination locations; each can be a local path, `hf://` URI, or `-` for stdin/stdout.",
      "Prerequisite: For Hub uploads, the docs say to log in to a Hugging Face account.",
      "Supports model-to-model, model-to-dataset, and other repository combinations.",
      "LFS blobs are deduplicated server-side; non-LFS files are fetched from the source repository and committed as regular payloads."
