Preview of File in List Report

The File Preview feature enables you to view files in a report before downloading them. You will be able view the file in a preview window.

Previewing will be applicable to fields that capture files: this includes file upload, image, audio, and video fields. When you click the file in one of these fields, a preview will be displayed. And if you need to download the file, there's a download button available in the preview window.

You will be able to navigate to the following and previous files within a record. This is applicable in both quick and detail views. Click the left and right arrows within the preview window to view files. If a record has information from related forms, the files in the related records can also be viewed while previewing. If you have subform field and that field has file upload or media fields, you will be able to obtain preview of those field values when you click on the said subform field.
