docs: Creates a file using the specified access condition, request options and operation context. If the file already
  exists, this will replace it.
  
  @param size
  A <code>long</code> which represents the size, in bytes, of the file.
  @param accessCondition
  An {@link AccessCondition} object which represents the access conditions for the file.
  @param options
  A {@link FileRequestOptions} object that specifies any additional options for the request. Specifying
  <code>null</code> will use the default request options from the associated service client (
  {@link CloudFileClient}).
  @param opContext
  An {@link OperationContext} object which represents the context for the current operation. This object
  is used to track requests to the storage service, and to provide additional runtime information about
  the operation.
  
  @throws StorageException
  If a storage service error occurred.
  @throws URISyntaxException
