public interface IDatabaseCompact
extends Serializable

Provides access to members for compacting a file or personal geodatabase.

Remarks

IDatabaseCompact is an optional interface supported by File and Personal geodatabases (Access Workspaces) which allows compaction of an Access database using the services of the Jet Engine or File geodatabases. After using a Personal or File geodatabase, the database may become fragmented on disk. The Compact method rearranges how a fragmented personal geodatabase is stored on disk or rearranges the files contained within a File Geodatabase workspace. Compacting a Personal or File geodatabase often reduces its size and improves its performance.

Using the IDatabaseCompact interface requires you to open a connection to the workspace. The Compact method on ILocalDatabaseCompact takes a WorkspaceName object as an argument, so it isn't necessary to open the workspace before compacting it.
