Unconvincing 2 1

Curious, I wanted to test this application which promises on paper to read files in .txt, .doc or even .epub. And the result is more than disappointing. For some reason, the application takes forever to show me a single directory on my device. I find it so impossible to navigate all the directories. So I had to copy the desired files in this single directory. And research by name always returns the web; more than frustrating.
After this painful moment, I discovered a French voice maddeningly (manic depression), which I can not, moreover, set the volume (fairly low). In addition, certain words are misread and ellipses are not made (the the University will be delivered entirely example).
In short, the application may be better with the English voice, but in French, it does not convince me. I uninstall.
