Set File Properties

The Set File Properties operation sets system properties on the file.

The Set File Properties request may be constructed as follows. HTTPS is recommended.

 

Method Request URI HTTP Version

PUT

https://myaccount.file.core.windows.net/myshare/mydirectorypath/myfile?comp=properties

HTTP/1.1

Replace the path components shown in the request URI with your own, as follows:

 

Path Component Description

myaccount

The name of your storage account.

myshare

The name of your file share.

mydirectorypath

Optional. The path to the parent directory.

myfile

The name of the file.

For details on path naming restrictions, see Naming and Referencing Shares, Directories, Files, and Metadata.

The following additional parameters may be specified on the request URI.

 

Parameter Description

timeout

Optional. The timeout parameter is expressed in seconds. For more information, see Setting Timeouts for File Service Operations.

The following table describes required and optional request headers.

 

Request Header Description

Authorization

Required. Specifies the authentication scheme, account name, and signature. For more information, see Authentication for the Azure Storage Services.

Date or x-ms-date

Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authentication for the Azure Storage Services.

x-ms-version

Required for all authenticated requests. Specifies the version of the operation to use for this request. For more information, see Versioning for the Azure Storage Services.

x-ms-cache-control

Optional. Modifies the cache control string for the file.

If this property is not specified on the request, then the property will be cleared for the file. Subsequent calls to Get File Properties will not return this property, unless it is explicitly set on the file again.

x-ms-content-type

Optional. Sets the file's content type.

If this property is not specified on the request, then the property will be cleared for the file. Subsequent calls to Get File Properties will not return this property, unless it is explicitly set on the file again.

x-ms-content-md5

Optional. Sets the file's MD5 hash.

If this property is not specified on the request, then the property will be cleared for the file. Subsequent calls to Get File Properties will not return this property, unless it is explicitly set on the file again.

x-ms-content-encoding

Optional. Sets the file's content encoding.

If this property is not specified on the request, then the property will be cleared for the file. Subsequent calls to Get File Properties will not return this property, unless it is explicitly set on the file again.

x-ms-content-language

Optional. Sets the file's content language.

If this property is not specified on the request, then the property will be cleared for the file. Subsequent calls to Get File Properties will not return this property, unless it is explicitly set on the file again.

x-ms-content-disposition

Optional. Sets the file’s Content-Disposition header.

If this property is not specified on the request, then the property will be cleared for the file. Subsequent calls to Get File Properties will not return this property, unless it is explicitly set on the file again.

x-ms-content-length: bytes

Optional. Resizes a file to the specified size. If the specified byte value is less than the current size of the file, then all ranges above the specified byte value are cleared.

The response includes an HTTP status code and a set of response headers.

A successful operation returns status code 200 (OK).

For information about status codes, see Status and Error Codes.

The response for this operation includes the following headers. The response may also include additional standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.

 

Response Header Description

ETag

The ETag contains a value which represents the version of the file, in quotes.

Last-Modified

Returns the date and time the directory was last modified. The date format follows RFC 1123. For more information, see Representation of Date/Time Values in Headers. Any operation that modifies the directory or its properties updates the last modified time. Operations on files do not affect the last modified time of the directory.

x-ms-request-id

This header uniquely identifies the request that was made and can be used for troubleshooting the request. For more information, see Troubleshooting API Operations.

x-ms-version

Indicates the version of the File service used to execute the request.

Date

A UTC date/time value generated by the service that indicates the time at which the response was initiated.

Only the account owner may call this operation.

The semantics for updating a file's properties are as follows:

  • A file's size is modified only if the request specifies a value for the x-ms-content-length header.

  • If a request sets only x-ms-content-length, and no other properties, then none of the file’s other properties are modified.

  • If any one or more of the following properties is set in the request, then all of these properties are set together. If a value is not provided for a given property when at least one of the properties listed below is set, then that property will be cleared for the file.

    • x-ms-cache-control

    • x-ms-content-type

    • x-ms-content-md5

    • x-ms-content-encoding

    • x-ms-content-language

noteNote
The file properties listed above are discrete from the file system properties available to SMB clients. SMB clients cannot read, write, or modify these property values.
