To visualize video clips on a Windows PC/laptop screen instead of just seeing the file titles, you can enable thumbnail views and the preview pane in your computer's file explorer. These settings work for files stored on external drives just as they do for internal ones.
Enable Thumbnails:
Open File Explorer and plug in your media.
Click the View tab in the top menu.
In the "Layout" section, select a view like Medium icons, Large icons, or Extra large icons.
If thumbnails still don't appear, click the three-dots menu (...) > Options > View tab. Uncheck the box for "Always show icons, never thumbnails" and click Apply.
Enable the Preview Pane:
In File Explorer, go to the View tab.
In the "Show" section, check the box for Preview pane (or use the shortcut Alt+P).
A pane will appear on the right. Clicking a video file should display its content, and you may even be able to play it within that pane.
