# D3D12_SHADER_CACHE_MODE

> Defines constants that specify a shader cache's mode.

Defines constants that specify a shader cache's mode.

## Syntax

```cpp theme={null}
typedef enum D3D12_SHADER_CACHE_MODE
{
    D3D12_SHADER_CACHE_MODE_MEMORY = 0,
    D3D12_SHADER_CACHE_MODE_DISK = 0
} D3D12_SHADER_CACHE_MODE
```

## Constants

| Constant                           | Description                                                                                                                                                                                                                                                                                                      |

| D3D12\_SHADER\_CACHE\_MODE\_MEMORY | Specifies that there's no backing file for this cache. All stores are discarded when the session object is destroyed.                                                                                                                                                                                            |
| D3D12\_SHADER\_CACHE\_MODE\_DISK   | Specifies that the session is backed by files on disk that persist from run to run unless cleared. For ways to clear a disk cache, see [ID3D12ShaderCacheSession::SetDeleteOnDestroy](/reference/graphics/d3d12/interfaces/id3d12shadercachesession/methods/id3d12shadercachesession_setdeleteondestroy_public). |
