iPhone X


Can we get iPhone X support



I have found this app highly useful. I like that I can move word docs, pdf's, mp3s, and other files from my computer. It gives my phone a desktop/laptop feel almost. I actually like to listen to music from my mp3s instead of the iPod in the phone. I also like that I can move files via email into the app and bypass having to sync up with iTunes on the computer. One improvement I'd say would be able to add files into a specific folder of choice. You can only drop files into the general place where all the folders and files are. It's a little cumbersome to then cut the files I've added and paste them one at time into the created folder for it. It would be nice if an update solved that. Otherwise, a very practical app that I use daily, and would gladly recommend.

Yay the second to last update made voice over work within files again.


I got the warning to turn off passwords, and made sure they were off. Took a deep breath hoping voice over would still fully function in the open files after update, and it did! Very happy to have access with voice over, without having to open in a separate app to read the file.
