Previewww Help

Table of contents

1. Introduction

Previewww enables previewing web sites in a preview pane of Windows Explorer by selecting Internet shortcuts from Windows Explorer folder. Previewww loads only textual contents of a web page and does not execute scripts. Previewww also loads and applies the external styles (CSS) linked to a web page (the styles can be disabled).

Internet shortcut is a Windows built-in file type which acts like a shortcut but instead of referring to local file it refers to a web page. Internet shortcut files may have extension .url or .website. The latter type of shortcut is known as Pinned Site Shortcut.

Previewww itself does not render the web page preview; instead, it utilizes system's built-in previewer for HTML and MHT files.

6. Known issues

  1. When clicking a link in preview pane the linked page should normally open in a web browser. This may fail, however, with the message about invalid link being displayed in the pane. To restore web page display deselect and select the shortcut or refresh the folder view by pressing <F5> or clicking View > Refresh from Windows Explorer menu.
  2. When dragging a link from preview pane Windows Explorer may hang and should be closed and restarted.
  3. Previewing may occasionally stop working, displaying "File can't be previewed" in preview pane. To resolve, temporarily set Internet Explorer as default web browser and double-click any Internet shortcut to open it in Internet Explorer. Then you can restore a browser of your choice as the default one.
