Structured Storage provides file and data persistence in COM by handling a single file as a structured collection of objects known as storages and streams.
The purpose of Structured Storage is to reduce the performance penalties and overhead associated with storing separate objects in a single file. Structured Storage provides a solution by defining how to handle a single file entity as a structured collection of two types of objects—storages and streams—through a standard implementation called Compound Files. This enables the user to interact with, and manage, a compound file as if it were a single file rather than a nested hierarchy of separate objects.
Structured Storage can be used on Microsoft COM-based operating systems.
The Structured Storage documentation is intended for experienced C and C++ programmers and COM-based system developers.
Structured Storage primarily supports C and C++ programming languages, however any COM-based technology will also support any programming language that utilizes interface pointers.
A solid understanding of COM technologies is prerequisite to the developmental use of Structured Storage.
For more information about which operating systems are required to use a particular API element, see the Requirements section of the documentation for the element.
