# PageFlushingPolicyEnum

PageFlushingPolicyEnum enumeration constants are used to denote the modes of working with document pages (with their [ImageDocument](/fine-reader/engine/api-reference/image-related-objects/imagedocument) and [Layout](/fine-reader/engine/api-reference/layout-related-objects/layout) objects) in memory.

```
typedef enum {
 PFP_KeepInMemory,
 PFP_FlushToDisk,
 PFP_Auto
} PageFlushingPolicyEnum;
```

| PFP\\\_FlushToDisk  | If there are no references to the ImageDocument and the Layout objects for corresponding pages, these objects should be unloaded and saved to disk. |
| PFP\\\_KeepInMemory | The document is always kept in memory.                                                                                                              |
