A handy, lightweight document viewer and printer.

STDU Viewer is a handy document viewing application which gives users the power and ability to view several different types of documents which would otherwise require an expensive office suite or clunky software.

This type of functionality is perfect on those occasions when you might receive a link to or an email containing content of which you don't have the software installed to view. STDU Viewer supports FB2, TXT, Comic Book Archive (CBR or CBZ), TCR, PalmDoc(PDB), MOBI, AZW, DCX and image (BMP, PCX, JPEG, GIF, PNG, WMF, EMF, PSD) files.

The overall user interface of this application is pretty nice and well organized. From there, you're able to view common formats which usually require third party support on Windows. Such examples include PDF, TXT, DOC and others.

The bookmarking feature of STDU Viewer is handy as it allows you to quickly access documents that you've marked as bookmarked.

This application is also fully capable of printing documents that it opens.

Finally, STDU Viewer is a very well programmed application which absolutely uses as little resources as possible to open documents. Usage is simple and this program is not clunky at all.
