Universal Viewer - Open Almost Any Files !

Universal Viewer, as its name implies, aims to be a universal file viewer capable of opening almost any file, without making you hunt down required programs for unusual file types.

Universal Viewer supports a wide variety of multimedia, image, and document formats.While it supports opening a truly vast array of file types, it doesn't support Microsoft Office documents unless Office is already installed. Other than that, most files are supported without any special work on your part. Universal Viewer also has a navigation panel, which allows for easier file navigation.

In addition to the file viewing, Universal Viewer also supports additional plug-ins and can convert nearly any document type to friendly old plain text.

Here's a list of formats the app supports out-of-the-box :

Text, Binary, Hex, Unicode: any files, of unlimited size (even 4Gb+ sizes are allowed)
RTF, UTF-8: RTF and UTF-8 encoded texts
Image: all general graphics formats: BMP JPG GIF PNG TGA TIFF... plus all formats supported by IrfanView/XnView external viewers
Multimedia: all formats supported by MS Windows Media Player: AVI MPG WMV MP3...
Internet: all formats supported by MS Internet Explorer: HTML PDF XML MHT...
Plugins: all formats supported by Total Commander Lister plugins
MS Office: all file types of MS Office (if installed): DOC DOCX XLS PPT...
Converters: some types can be viewed as plain text: DOC DOCX PDF PPT ODT...

The application integrates into Windows Explorer's context menu, so all you need to do is right-click a file and select "Universal Viewer." In addition, it can also be integrated into other popular file managers. Universal Viewer is a freeware application for Windows platforms only. Got a similar tool you use to fill this need, or do you just hunt down and install whatever apps need installing when you need them?
