Whislt some files are not designed to be viewed the application recognized certain file types even if it cannot view them.
I had success with PDF, Word DOC & DOCX, Excel, PowerPoint PPT & PPTX (scroll and view all slides), JPG, RAW, GIF, PNG, ICS, PAGES, ODT, TAR, TXT, TIFF, ZIP, RTF, MOV (playable), m4a (playable), mp4 (playable), mp3 (playable). Drag and drop files to the 'Open All Files' window to view file contents.
