Azure Storage File Share SDK for Python

Manage SMB file shares for cloud-native and lift-and-shift scenarios.

Installation

pip install azure-storage-file-share

Environment Variables

AZURE_STORAGE_ACCOUNT_URL=https://<account>.file.core.windows.net  # Required for Entra ID auth
AZURE_TOKEN_CREDENTIALS=prod # Required only if DefaultAzureCredential is used in production

Authentication & Lifecycle

> 🔑 Two rules apply to every code sample below:

>

> 1. Prefer DefaultAzureCredential. It works locally (Azure CLI / VS Code / Developer CLI) and in Azure (managed identity, workload identity) with no code change. Avoid connection strings, account/API keys — they bypass Entra audit and rotation.

> - Local dev: DefaultAzureCredential works as-is.

> - Production: set AZURE_TOKEN_CREDENTIALS=prod (or AZURE_TOKEN_CREDENTIALS=<specific_credential>) to constrain the credential chain to production-safe credentials.

> 2. Wrap every client in a context manager so HTTP transports, sockets, and token caches are released deterministically:

> - Sync: with <Client>(...) as client:

> - Async: async with <Client>(...) as client: and async with DefaultAzureCredential() as credential: (from azure.identity.aio)

>

> Snippets may abbreviate this setup, but production code should always follow both rules.

from azure.storage.fileshare import ShareServiceClient
from azure.identity import DefaultAzureCredential, ManagedIdentityCredential

# Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>
credential = DefaultAzureCredential(require_envvar=True)
# Or use a specific credential directly in production:
# See https://learn.microsoft.com/python/api/overview/azure/identity-readme?view=azure-python#credential-classes
# credential = ManagedIdentityCredential()

with ShareServiceClient(
    account_url=os.environ["AZURE_STORAGE_ACCOUNT_URL"],
    credential=credential
) as service:
    # Use service here (see following sections for operations)
    ...

Share Operations

Create Share

share = service.create_share("my-share")

List Shares

for share in service.list_shares():
    print(f"{share.name}: {share.quota} GB")

Get Share Client

share_client = service.get_share_client("my-share")

Delete Share

service.delete_share("my-share")

Directory Operations

Create Directory

share_client = service.get_share_client("my-share")
share_client.create_directory("my-directory")

# Nested directory
share_client.create_directory("my-directory/sub-directory")

List Directories and Files

directory_client = share_client.get_directory_client("my-directory")

for item in directory_client.list_directories_and_files():
    if item["is_directory"]:
        print(f"[DIR] {item['name']}")
    else:
        print(f"[FILE] {item['name']} ({item['size']} bytes)")

Delete Directory

share_client.delete_directory("my-directory")

File Operations

Upload File

file_client = share_client.get_file_client("my-directory/file.txt")

# From string
file_client.upload_file("Hello, World!")

# From file
with open("local-file.txt", "rb") as f:
    file_client.upload_file(f)

# From bytes
file_client.upload_file(b"Binary content")

Download File

file_client = share_client.get_file_client("my-directory/file.txt")

# To bytes
data = file_client.download_file().readall()

# To file
with open("downloaded.txt", "wb") as f:
    data = file_client.download_file()
    data.readinto(f)

# Stream chunks
download = file_client.download_file()
for chunk in download.chunks():
    process(chunk)

Get File Properties

properties = file_client.get_file_properties()
print(f"Size: {properties.size}")
print(f"Content type: {properties.content_settings.content_type}")
print(f"Last modified: {properties.last_modified}")

Delete File

file_client.delete_file()

Copy File

source_url = "https://account.file.core.windows.net/share/source.txt"
dest_client = share_client.get_file_client("destination.txt")
dest_client.start_copy_from_url(source_url)

Range Operations

Upload Range

# Upload to specific range
file_client.upload_range(data=b"content", offset=0, length=7)

Download Range

# Download specific range
download = file_client.download_file(offset=0, length=100)
data = download.readall()

Snapshot Operations

Create Snapshot

snapshot = share_client.create_snapshot()
print(f"Snapshot: {snapshot['snapshot']}")

Access Snapshot

snapshot_client = service.get_share_client(
    "my-share",
    snapshot=snapshot["snapshot"]
)

Async Client

from azure.storage.fileshare.aio import ShareServiceClient
from azure.identity.aio import DefaultAzureCredential

async def upload_file():
    async with DefaultAzureCredential() as credential:
        async with ShareServiceClient(account_url, credential=credential) as service:
            share = service.get_share_client("my-share")
            file_client = share.get_file_client("test.txt")
            
            await file_client.upload_file("Hello!")

Client Types

| Client | Purpose |

|--------|---------|

| ShareServiceClient | Account-level operations |

| ShareClient | Share operations |

| ShareDirectoryClient | Directory operations |

| ShareFileClient | File operations |

Best Practices

  • Pick sync OR async and stay consistent. Do not mix azure.storage.fileshare sync clients with azure.storage.fileshare.aio async clients in the same call path. Choose one mode per module.
  • Always use context managers for clients and async credentials. Wrap every client in with ShareServiceClient(...) as client: (sync) or async with ShareServiceClient(...) as client: (async). For async DefaultAzureCredential from azure.identity.aio, also use async with credential: so tokens and transports are cleaned up.
  • Use DefaultAzureCredential for portable auth across local dev and Azure (avoid connection strings / API keys when possible).
  • Use Microsoft Entra ID for production with RBAC
  • Stream large files using chunks() to avoid memory issues
  • Create snapshots before major changes
  • Set quotas to prevent unexpected storage costs
  • Use ranges for partial file updates

How to use it

Copy the folder

Take microsoft/azure-storage-file-share-py from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference pip. Without those the skill loads but fails at the first command.
