This page provides an overview of those tools.\n\nOverview\n--------\n\nCloud Storage buckets store objects in a [flat namespace](/storage/docs/objects#flat-namespace) but there are\nmultiple tools you can use to interact with your stored data in a directory\nstructure, similar to file systems. These tools provide the following\ncapabilities:\n\n- **Structuring your data**: Group related objects into folders,\n making it easier to navigate and manage your data.\n\n- **Controlling access to object groups**: Set up granular access\n control for your objects, enabling you to specify who can view, edit, or\n delete specific sets of data within a bucket.\n\n### Simulated folders\n\n[Simulated folders](/storage/docs/objects#simulated-folders) in Cloud Storage are a way to create a visual\nhierarchy and organize objects within a bucket without actually creating folder\nstructures. Using the Google Cloud console and Google Cloud CLI, you can simulate\nfolders that mimic the file tree to help you organize data in your bucket.\nSimulated folders are implemented by using prefixes or delimiters, separated by\na forward slash `/` within object names.\n\n### Folders in buckets with hierarchical namespace enabled\n\nIn buckets with [hierarchical namespace](/storage/docs/hns-overview) enabled, you can create actual\nfolders that contain objects or other folders. You can also perform operations\nlike renaming folders and listing folders. The hierarchical structure and folder\nmanagement operations improve performance, consistency, and management for\nfile-oriented and data-intensive workloads.\n\nFor more information about folders, see\n[About folders in buckets with hierarchical namespace enabled](/storage/docs/folders-overview).\n\n### Managed folders\n\n[Managed folders](/storage/docs/managed-folders) enable you to apply granular access controls to your\nobjects, enhancing security and control over your data. You can use managed\nfolders in buckets with or without hierarchical namespace enabled. Unlike\nsimulated folders which use prefixes, managed folders are actual\nresources within the bucket, enabling you to apply Identity and Access Management (IAM)\npolicies to groups of objects.\n\nTo get started using managed folders, see [Create managed folders](/storage/docs/creating-managing-managed-folders).\n\nWhat's next\n-----------\n\n- Learn about [simulated folders](/storage/docs/objects#simulated-folders).\n- Learn about [enabling hierarchical namespace for your bucket](/storage/docs/hns-overview).\n- Learn about [managed folders](/storage/docs/managed-folders)."]]
