Hi Micheal,
Thanks for taking the time out to help.
I do overcome the problem of moving apps from the root directory….. . . Something like this..
I made a Backup using the Android settings window
USing a file manager I copied the back up folder to my SD card, and then moved an app (an unimportant chess game which I knew I could easily restore) from that folder directly to the SD card. . . I then launched that copy in file manager. The system then asked if I wanted to update this version, which I did. . . I then deleted all the Backup copies, leaving just one file.
This worked…. . . But there must be a more professional way…..very long winded……….
