It supports nearly every file format you can think of. Other than Real Media files, the Acloon VideoViewer can play just about any multimedia file type you're likely to come across. If that was the sum total of Acloon VideoViewer's niftiness I wouldn't have even bothered to write this far. The reason it's worth the 20 odd smackers is because of how it integrates itself into your Windows shell. Right on the regular right click context menu you'll see the normal options like cut, copy, paste, delete, and so on but with Acloon VideoViewer you'll also see the multimedia file itself.
Images display, audio plays, videos run, all right there on the menu.
No more guessing what files are, no more loading up clip after clip just to find that one single one you need. With Acloon VideoViewer it's as simple as browse, click, and view.
