A few reasons I'll stick with a different app – Briefcase Pro - File manager, cloud drive, document & pdf reader and file sharing App Review

First off, upon launch one of the first things I notice is my firewall reports the app is - like most apps these days - reaching out to Facebook to start gathering the data harvest. I know almost every app does this, but I am on of the few people left remaining who hasn't been brainwashed into just accepting this as okay. It's not, and I hold it against the developer. I do still have lots of well designed apps who's developers put a lot of hard work into, that don't play the data money game. Then, upon tapping "other cloud drives" the app crashed. So there's that. I will stick with File Browser, by Stratospherx. They've consistently kept the app the very best of its kind, and I communicate with the developer often to suggest features or ask about complex tasks. Nice try, but this app is sloppy and in a rush to start paying tithe to the data gods, sacrificing the user in doing so.
