ILayoutStorage interface

The ILayoutStorage interface enables an application to optimize the layout of its compound files for efficient downloading across a slow link. The goal is to enable a browser or other application to download data in the order in which it will actually be required.

To optimize a compound file, an application calls CopyTo to layout a docfile, thus improving performance in most scenarios.

When to implement

You do not need to implement this interface. A special implementation of Compound Files exposes ILayoutStorage on the root storage object.

When to use

Use ILayoutStorage to optimize your application's compound files.
