## Document.packageCustomParts property

Gets or sets the collection of custom parts (arbitrary content) that are linked to the OOXML package using "unknown relationships".


```js
get packageCustomParts(): Aspose.Words.Markup.CustomPartCollection
```

### Remarks

Do not confuse these custom parts with Custom XML Data. If you need to access Custom XML parts,
use the [Document.customXmlParts](../customXmlParts/) property.

This collection contains OOXML parts whose parent is the OOXML package and they targets are of an "unknown relationship".
For more information see [CustomPart](../../../aspose.words.markup/custompart/).

Aspose.Words loads and saves custom parts into OOXML documents only.

This property cannot be ``null``.
