The function of the Ribbon toolbar of Win8 File Explorer makes us raspberry, and there is a gadget that can be used for our daily use, which is the preview pane. How does Win8.1 use this gadget?
Click the File Explorer icon in the taskbar to open the Library window, or double-click this computer on your desktop to open the Computer window, and then switch to the view ribbon.
Click the preview Pane button and select a document (Common txt, word, PPT, etc.) or a picture to preview the contents of the document or picture in the preview space on the right.
Win8.1 File Explorer When you select the Feature button for preview pane, the right side of the main pane displays the contents of the selected file without having to open the file again. This is different from the details pane feature of another tool in the Ribbon toolbar, which displays information about the file such as the modified date.
