Docx and excel files all working without an issue and without any appreciable loading lag

It works with the free powerreader app from the app store you’re cued to download it the first time you use the device and then to use it every time you plug the device in but i had one complaint – each photo file raw or jpeg had to be opened and closed individually – you couldn’t just swipe to see the next picture

It displays my videos and raw files without a problem and i have also tested it with jpeg pdf
