Lightning FileCard displays a preview of the file. If you use this component on the desktop, and after clicking on files preview it opens the file in the SVG file preview player in lightning experience. This enables you to preview the image, document, and other files in the browser. If you are using this component on mobile and after clicking on the preview download the files.
This “FileCard” component can be added to the sObject (Account, Contact, Opportunity, etc.) detail page. This component will show all uploaded files with previews on the sObject records. You only need to use lightning app builder to add the component to the record page.
This component displays a preview of the uploaded file, allowing the user to quickly determine which file is being uploaded.
