Parameters
Name | Description |

Required
|
The URI to the storage account. In order to create a client given the full URI to the file, use the from_file_url classmethod. |
share_name
Required
|
The name of the share for the file. |
file_path
Required
|
The file path to the file with which to interact. If specified, this value will override a file value specified in the file URL. |
snapshot
|

|
If true, the trailing dot will not be trimmed from the source URI. |

Methods
abort_copy |
Abort an ongoing copy operation. This will leave a destination file with zero length and full metadata. This will raise an error if the copy operation has already ended. |
acquire_lease |
Requests a new lease. If the file does not have an active lease, the File Service creates a lease on the blob and returns a new lease. |
clear_range |
Clears the specified range and releases the space used in storage for that range. |
close |
This method is to close the sockets opened by the client. It need not be used when using with a context manager. |
close_all_handles |
Close any open file handles. This operation will block until the service has closed all open handles. |
close_handle |
Close an open file handle. |
create_file |
Creates a new file. Note that it only initializes the file with no content. |
delete_file |
Marks the specified file for deletion. The file is later deleted during garbage collection. |
download_file |
Downloads a file to the StorageStreamDownloader. The readall() method must be used to read all the content or readinto() must be used to download the file into a stream. Using chunks() returns an iterator which allows the user to iterate over the content in chunks. |
exists |
Returns True if the file exists and returns False otherwise. |
from_connection_string |
Create ShareFileClient from a Connection String. |
from_file_url |

Maximum number of parallel connections to use when transferring the file in chunks. This option does not affect the underlying connection pool, and may require a separate configuration of the connection pool. |

This is primarily valuable for detecting bitflips on the wire if using http instead of https as https (the default) will already validate. Note that this MD5 hash is not stored with the file. Also note that if enabled, the memory-efficient upload algorithm will not be used, because computing the MD5 hash requires buffering entire blocks, and doing so defeats the purpose of the memory-efficient algorithm. |
