# SaveFileDialogOptions.Filter property

The file type filters, written as display name and patterns alternating and separated by `|`, where several patterns for one type are separated by `;` and each pattern is a glob such as `*.png` — for example `"Images|*.png;*.jpg|All files|*.*"`. Ignored when [`FilterFileTypes`](./FilterFileTypes.md) is set.

```csharp
public string? Filter { get; set; }
```
