Thanks Jh,
An excellent suggestion which works on Drive. Unfortunately the data volume is large and internet speed very poor.
I had looked at other apps - without success, but will look at the new references (dubious because of basic link issue - input to iPad).
I have also used File Explorer for two-stage transfer via hard drive connected to router - as identified, with success, in an earlier thread. Slow internet !
Just hoping that the single-stage transfer via Bluetooth would be faster.
Also now ‘playing’ with the idea of cable transfer between Android and iPad using the lates iPad software update.
P.S. Now established Bluetooth contact after resetting A60 tethering; unfortunately files still not being sent.
