# XPackageChunkAvailability

> XPackageChunkAvailability

Indicates the availability of installation chunks.

## Syntax

```cpp theme={null}
enum class XPackageChunkAvailability  : uint32_t  
{  
    Ready,  
    Pending,  
    Installable,  
    Unavailable  
}  
```

## Constants

| Constant | Description |
| - | - |
| Ready | The chunk is already installed and can be read. |
| Pending | The chunk is not installed yet but will be. |
| Installable | The chunk will not be installed but can be downloaded. |
| Unavailable | The chunk can't be downloaded. |

## 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.
