Didn't ask for it to take over my computer's. . .

capability for opening files with default apps. I was hoping this would open some oddball files I have lying around (much like the old app CanOpener). Instead it appeared to change the file creator type/open with for pretty much everything to use this app. Maybe I misunderstood what it's for, but to me it just does what's already built in to the macOS. Oh yeah: the developer should thank their lucky stars I know how to restore the default apps/file types, because that's what I had to do.

This app went to big software Trash dumpster.

Excellent and works exactly as described

Simple and easy to use. Drag and drop files to the "Open All Files" window to view file contents. 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). Whislt some files are not designed to be viewed the application recognized certain file types even if it cannot view them. Sure there are some proprietary file types like Visio VSDX or other Visio template files, that it is not currently capable of displaying but for the most part this is an awesome little viewer that can be used in a pinch to view almost anything. Obviously with some caveats of course, it can’t view absolutely everything biut does most everyday files you will likely use apart from some specific applications. Having tried and used many viewer apps on multiple platforms I can say that this utility is a gem worth having on your system. I’m impressed with its capabilities.

Complete DISASTER!

This installed ok (from what I could see), but opening it completely FROZE my Macbook. I had to do a hard shutdown! On a reboot, the app was still opened and, once again, everything froze up. I had to go into Safe Boot to drag this garbage to the trash. I cannot EVEN believe Apple would allow such a disaster in their app store! Buyer BEWARE.
