## Remarks

This enumeration determines the status and availability of the XPackage API installation files. Packages contain all the files that make up a game. Files can be grouped into logical units called chunks. A chunk has a numeric ID and can also have zero or more textual attributes like a language or a user-defined tag. Many XPackage APIs operate on groups of chunks.

For information about the packaging technology used with XBOX One titles, see [Overview of Packaging](/build/core-features/common/packaging/overviews/packaging). For information about the steps to create an XVC package, see [Getting started packaging titles for XBOX consoles](/build/core-features/common/packaging/overviews/packaging-getting-started-for-console).
