I appreciate your response, thanks, but I need to move files around on the SD card; like documents from Google Drive, and I can do it on my Note 4 with Lollipop, but not on my Note Edge.
This is a serious work device for me, not just a toy for music and pictures.
What about downloading a different file manager like ES File Explorer from the Play Store? I have never owned a phone that didn't have a file manager. The only Samsung I ever had was a G Nexus and even it had a FE on it. Using Google Drive, when I download from mine it goes to my Downloads folder, which on my LGs and the Gnex I had a Downloads icon in the app drawer.
ES File Explorer is my go-to, and it doesn't work.
"Your system forbids ES from writing on external SD card (check https://code.google.com/p/android/issues/detail?id=67570), so ES can only write on it after rooted."
