### Examples

Shows how to resolve URLs like "ms-its:myfile.chm::/index.htm".

```js
// Our document contains URLs like "ms-its:amhelp.chm::....htm", but it has a different name,
// so file links don't work after saving it to HTML.
// We need to define the original filename in 'ChmLoadOptions' to avoid this behavior.
let loadOptions = new aw.Loading.ChmLoadOptions();
loadOptions.originalFileName = "amhelp.chm";

let doc = new aw.Document(base.myDir + "Document with ms-its links.chm", loadOptions);

doc.save(base.artifactsDir + "ExChmLoadOptions.originalFileName.html");
```
