I went shopping on iTunes for a simple document transfer app. There are a lot of good ones that make use of a cloud, but I wanted one that was between my iPad and me. USB Disk for iPad and USB Disk Pro for iPad were just what I needed. Using iTunes, you can easily transfer files from your drives to the app. Once the files are in the app, you can create folders, move them from one folder to the next and view the files. It is a handy way to store documents you use regularly.
This app (I use the pro version) gets a thumbs up for sustainability. I’ve had it downloaded for two years and continue to find it valuable.
