For information about path naming restrictions, see Name and reference shares, directories, files, and metadata.

URI parameters

The following additional parameters may be specified in the request URI:

Parameter Description
sharesnapshot Optional. Version 2017-04-17 and later. The sharesnapshot parameter is an opaque DateTime value that, when present, specifies the share snapshot to query for the file metadata.
timeout Optional. The timeout parameter is expressed in seconds. For more information, see Set time-outs for Azure Files operations.

Request headers

The required and optional request headers are described in the following table:

Request header Description
Authorization Required. Specifies the authorization scheme, account name, and signature. For more information, see Authorize requests to Azure Storage.
Date or x-ms-date Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authorize requests to Azure Storage.
x-ms-version Required for all authorized requests. Specifies the version of the operation to use for this request. For more information, see Versioning for the Azure Storage services.
x-ms-lease-id:<ID> Optional. Version 2019-02-02 and later. If the header is specified, the operation is performed only if the file's lease is currently active and the lease ID that's specified in the request matches the lease ID of the file. Otherwise, the operation fails with status code 412 (Precondition Failed).
x-ms-client-request-id Optional. Provides a client-generated, opaque value with a 1-kibibyte (KiB) character limit that's recorded in the logs when logging is configured. We highly recommend that you use this header to correlate client-side activities with requests that the server receives. For more information, see Monitor Azure Files.
x-ms-file-request-intent Required if Authorization header specifies an OAuth token. Acceptable value is backup. This header specifies that the Microsoft.Storage/storageAccounts/fileServices/readFileBackupSemantics/action or Microsoft.Storage/storageAccounts/fileServices/writeFileBackupSemantics/action should be granted if they are included in the RBAC policy assigned to the identity that is authorized using the Authorization header. Available for version 2022-11-02 and later.
x-ms-allow-trailing-dot: { <Boolean> } Optional. Version 2022-11-02 and later. The Boolean value specifies if a trailing dot present in request url should be trimmed or not. For more information, see Naming and referencing shares, directories, files, and metadata.

Response header Description
Last-Modified Returns the date and time when the file was last modified. The date format follows RFC 1123. For more information, see Represent date/time values in headers. Any operation that modifies the file or its properties updates the last modified time.
x-ms-meta-name:value A set of name-value pairs that contain metadata for the file.
x-ms-type: <File> Returns File and is reserved for future use.
x-ms-request-id Uniquely identifies the request that was made, and it can be used to troubleshoot the request. For more information, see Troubleshoot API operations.

Date or x-ms-date A UTC date/time value that's generated by the service, which indicates the time when the response was initiated.
x-ms-client-request-id This header can be used to troubleshoot requests and corresponding responses.
