Most of us are used to opening PDF files with a special viewer, be it Acrobat Reader or something else. But what happens when you have other files that require special viewers? Are you supposed to just keep cluttering up your hard drive with new programs? STDU Viewer Portable is a document viewer that can handle not only PDF files, but a variety of other common and uncommon file types.
STDU Viewer Portable looks just like many other document viewers, with a set of menus across the top and a toolbar just below. We were impressed with the number of different file types that STDU Viewer Portable can handle; in addition to PDF files, the program can also open DjVu, TIFF, XPS, Comic Book Archive, text, image, FB2, JBIG2, PalmDoc, WWF, and PCX files. We liked that the program can display multiple files at once in its tabbed interface. You can also export files in a variety of text or image formats, making it easy to share files that are in formats that can't be opened by friends or colleagues. There's no Help file, so if you don't already know about some of the more-obscure file types that STDU Viewer Portable supports, you'll have to look elsewhere for more information. But for people who know what they're doing -- namely, trying to open a variety of different file types without using a variety of different programs -- STDU Viewer Portable is a great choice. The fact that it can be stored on a USB drive or other portable device makes it even better.
STDU Viewer Portable comes as a ZIP file and is accessible after extraction with no need for installation.
