Universal Viewer (ATViewer)
Latest version: 18.104.22.168 (26 Nov 2006)
Is an advanced file viewer with wide range of formats supported. Implemented view modes and corresponding file formats are:
Text/Binary/Hex/Unicode: all files, with unlimited file 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 etc; Multimedia: all formats supported by MS Window Media Player: AVI MPG WMV MP3 MIDI etc;
Internet: all formats supported by MS Internet Explorer: HTML XML DOC XLS etc;
Plugins: all formats supported by Total Commander Lister plugins. The Viewer is fully Unicode compatible and can be integrated into Windows Explorer's context menu, so there is no problem to call it from anywhere in Explorer: right-click on a file and select "Universal Viewer" item. It can also be integrated into file managers that can pass to Viewer filenames via the command-line: in this case filename should be passed as first optional command parameter (don't forget to double-quote name containing spaces).
