Structured Storage Fundamentals
Structured Storage provides the equivalent of a complete file system for storing objects through the elements listed in the following table.
| Element | Description |
|---|---|
| Structured Storage Interfaces | The IStorage, IStream, ILockBytes, and IRootStorage interfaces, along with a set of related interfaces —IPersistStorage, IPersist, IPersistFile, and IPersistStream. |
| Structured Storage API Functions | Helper APIs that facilitate an implementation of structured storage, as well as a second set of APIs for compound files; that is the COM implementation of the structured storage interfaces. COM also provides a set of supporting structures and enumeration values used to organize parameters for interface methods and APIs. |
| Structured Storage Access Modes | A set of access modes for regulating access to compound files. |
