handleRename method

Implementation

    return;
  }

    return;
  }

  // Parse the rename command arguments (oldname newname)
  final parts = argument.split(' ');
  if (parts.length != 2) {
    session.sendResponse('501 Syntax error in parameters or arguments');
    return;
  }

  final oldName = parts[0];
  final newName = parts[1];

  // Check if the file/directory exists
  if (!session.fileOperations.exists(oldName)) {

    return;
  }

  try {

    session.renameFileOrDirectory(oldName, newName);
  } catch (e) {
