    size: 1000,
    date: new Date(2023, 10, 30, 6, 13),
    type: "file",
  },
];

const drive = {
  used: 15200000000,
  total: 50000000000,
};

function App() {
  const handleSelectFile = (ev) => {
    console.log("File selected:", ev.id);
  };

  const handleRenameFile = (ev) => {
    console.log("File renamed:", ev.id, "to", ev.name);
  };

  const handleDeleteFiles = (ev) => {
    console.log("Files deleted:", ev.ids);
  };

  const handleCopyFiles = (ev) => {
    console.log("Files copied:", ev.ids, "to", ev.target);
  };

  const handleMoveFiles = (ev) => {
    console.log("Files moved:", ev.ids, "to", ev.target);
  };

  const handleCreateFile = (ev) => {
    console.log("File created:", ev.id, "type:", ev.type);
  };

  const handleUploadFiles = (ev) => {
    console.log("Files uploaded to:", ev.to, "files:", ev.files);
  };

  return (
    <Filemanager

  used: 15200000000,
  total: 50000000000,
};

function App() {
  const apiRef = useRef(null);

  const init = useCallback((api) => {
    apiRef.current = api;

    // Intercept delete operations to prevent deleting critical files
    api.intercept("delete-files", (ev) => {
      const hasCritical = ev.ids.some(id => id.includes("critical"));
      if (hasCritical) {
        alert("Cannot delete critical files!");
        return false; // Cancel the operation
      }
      return true; // Allow operation to proceed
    });

    // Intercept rename operations to enforce naming conventions
    api.intercept("rename-file", (ev) => {
      if (ev.name.includes(" ")) {
        alert("File names cannot contain spaces!");
        return false;
      }
      return true;
    });

    // Listen to path changes
    api.on("set-path", (ev) => {
      console.log("Navigation to:", ev.id);
    });

    // Get current state
    const state = api.getState();
    console.log("Current path:", state.panels[0].path);
    console.log("Selected files:", state.selected);
  }, []);

  return (
    <Filemanager
      ref={apiRef}
      init={init}
      data={files}
      drive={drive}
    />
  );

  useEffect(() => {
    // Listen to server file rename events
    restProvider.on("file-renamed", ({ id, newId }) => {
      const name = newId.slice(newId.lastIndexOf("/") + 1);
      fmApiRef.current.exec("rename-file", { id, name, skipProvider: true });
    });

    // Load initial data from server
    Promise.all([restProvider.loadFiles(), restProvider.loadInfo()]).then(
      ([files, info]) => {
        setData(files);
        setDrive(info);
      }
    );
  }, [restProvider]);

  const loadData = useCallback((ev) => {
    const id = ev.id;
    restProvider.loadFiles(id).then((files) => {
      fmApiRef.current.exec("provide-data", {
        id,
        data: files,
      });
    });
  }, [restProvider]);

  return (
    <Filemanager
      init={init}
      data={data}
      drive={drive}
      icons={iconsURL}
      previews={previewURL}
