Works well!

I installed File Storage Companion on my desktop Mac but then couldnt find "File Storage" on my iPads version of the App Store. However, I did find it through iTunes and purchased it there. It appeared right away on my tethered iPad. I launched File Storage on the iPad, enabled WiFi within the app (there is a prompt), and the device was instantly recognized on my desktop Mac. File transfer was instantaneous. However, WiFi Sharing had to be terminated on the iPad before I could access the Home directory and see the file listed there.
