Adds a possibility to upload **multipe files at once** in order to add them to the ordering item. This Option uploads a file via AJAX in chunks, so it can handle file upload of any sizes regardless

```
max_file_upload
```

setting on your hosting. 💪 It is possible to restrict files by size and by MIME types.

Some settings related to this Option are on [plugin's settings](/uni-cpo-4-documentation/usage/plugins-settings.md) page. These settings are global and automatically applied to all instances of File Upload Option. However, setting like *max file size* and \_mime types allowed \_can be overridden on per Option instance basis. It means that you can have fine tuned file uploads across the site! 😎
