# About Storage Buckets

> Storage buckets provide a per-folder storage solution for RPA developers to leverage in creating automation projects (e.g. for a `.pdf` file used across multiple business processes or data sets used for your machine learning models). For details on using storage buckets in your automation projects read about [Orchestrator activities](https://docs.uipath.com/activities/other/latest/workflow/system-activities) in the Activities guide.

Storage buckets provide a per-folder storage solution for RPA developers to leverage in creating automation projects (e.g. for a `.pdf` file used across multiple business processes or data sets used for your machine learning models). For details on using storage buckets in your automation projects read about [Orchestrator activities](https://docs.uipath.com/activities/other/latest/workflow/system-activities) in the Activities guide.

As storage buckets are created within the scope of a given folder, this enables you to use the fine-grained permissions and role assignment models of the Folders feature to control access to these storage buckets and their contents only to those accounts that need it. Users with the required permissions can browse the contents of any configured storage bucket, and upload or download files as desired.

The **Storage Buckets** page displays your currently configured buckets and enables you to create as many additional storage buckets as needed.

## Storage Providers

Use any of the following providers to configure storage buckets:

* **Orchestrator** - the same storage location where Orchestrator feed packages are kept (check the **[Deployment](https://docs.uipath.com/orchestrator/standalone/2024.10/installation-guide/uipath-orchestrator-dll-config#deployment)** section of the **UiPath.Orchestrator.dll.config** topic)
* **Azure Storage (WASB)**
* **MinIO**
* **S3 Compatible** storage solutions - support SSE-KMS
* **FileSystem** - the file system location of your choice (check the **[Storage Buckets](https://docs.uipath.com/orchestrator/standalone/2024.10/installation-guide/uipath-orchestrator-dll-config#storage-buckets)** section of the **UiPath.Orchestrator.dll.config** topic)
:::note
* For connecting to AWS S3 buckets or S3-compatible buckets, Orchestrator uses signature V4 by default, in all configurations.
If you want to enable the old behavior, where V2 signatures were used for `us-east-1` or for your S3-compatible storage provider, you need to add the `Aws.UseSignatureVersion4` setting to the `UiPath.Orchestrator.dll.config` file, with the value `false`.
:::

To specify which providers can be used in creating storage buckets in Orchestrator you must proceed as follows:

1. Open the `UiPath.Orchestrator.dll.config` file in the Orchestrator installation folder.
2. Specify the desired storage providers using the `Buckets.AvailableProviders` setting. For example, add the following key in the `UiPath.Orchestrator.dll.config` file to enable Orchestrator, Amazon, Azure, MinIO and S3 compatible storage providers: `<add key="Buckets.AvailableProviders" value="Orchestrator,Amazon,Azure,Minio,S3Compatible" />`. See the dedicated [Buckets.AvailableProviders section](https://docs.uipath.com/orchestrator/standalone/2021.10/installation-guide/uipath-orchestrator-dll-config#bucketsavailableproviders) in the Installation and Upgrade guide for details.
3. Restart Orchestrator.
   :::important
   FileSystem is disabled by default on both new installations and upgrades. To enable this provider, you need to explicitly specify it as a [Buckets.AvailableProviders](https://docs.uipath.com/orchestrator/standalone/2022.4/installation-guide/uipath-orchestrator-dll-config#bucketsavailableproviders) value in the `UiPath.Orchestrator.dll.config` file, and then add the FileSystem paths to an allowlist using the [Buckets.FileSystem.Allowlist](https://docs.uipath.com/orchestrator/standalone/2022.4/installation-guide/uipath-orchestrator-dll-config#bucketsfilesystemallowlist) setting. Considering that creating a FileSystem allowlist via the `Buckets.FileSystem.Allowlist` setting has a series of security implications, you are strongly advised to refer to [Using the FileSystem Storage Allowlist Securely](https://docs.uipath.com/orchestrator/standalone/2021.10/installation-guide/using-the-filesystem-storage-allowlist) before proceeding.
