WPF:ListView Remove SelectedItem from ImageFileCollectionViewModel

I have a listView which loads images from a directory using the 'ImageViewCollectionModel' along with the 'FileViewModel' .

I have 2 button, one button to 'Delete' the selected image and another button to 'View' the selected image.

When I want to delete, I want to delete from the ListView and also from the directory. Please help me to remove the selected item from the list & also from
the directory. Thank you.

ListView:
