# Filters

## **Filter: FileBird Post Types**

*  Description: Add Or Remove post type supported in FileBird Pro 
* Code example:

```
add_filter('filebird_post_types', function($post_types) {
	unset($post_types['post']);
	return $post_types;
});
```

## **Filter: Zip File with ZipStream**

*  Description: FileBird will automatically detect if ZipStream is currently installed on your PHP server, and if it’s not, it will automatically switch to using ZipArchive. The filter ‘fbv\_use\_zipstream’ helps us switch to ZipArchive if your system is currently running ZipStream but encounters an issue.
* Code example:

```
// Using ZipStream
add_filters( 'fbv_use_zipstream', '__return_true' );
// Using ZipArchive
add_filters( 'fbv_use_zipstream', '__return_false' );
```
