The Windows Explorer replacement tool, xplorer², has a "Quck View" function, where it can do rather more than just show the first page of a file. For example, for any file you select (not hover) it can give you things like:
* display the draft and native content of a .pdf file.
* display the draft and native contents of a Word file.
* display the contents of a .txt file.
* display an image file.
* play an .mp3 or other (sound file).
* play a video file (various formats).
* it will also display the text in many other files (e.g., html files, script files).
The display is made in a special Quick View window that is opened when you select Quick View. All you need to do is scroll through the files to see the display of contents.
