Thanks to all of you for making good suggestions but I can faithfully report that as of today 19th May 2015 I have now used 1) HTC sync Manager 2) Realplayer Cloud (to some reasonable use) and 3) Airdroid (which doesn't recognise my 128GB memory card. After scores of hours working these programs in unison and imaginatively separately I was able to load some songs and their respective playlists. The photos loaded by groups and then over several days the count dropped and the remaining files were displayed chopped in half or corrupt. Videos said no way and the Playlists evaporated to now showing 30 listed playlists with no contents. The music files are however resident on the mem card but its colossal. The Software managers wont talk anymore to the device and the HTC excuse for a program is still orbiting the Earth from last launch. I tried loading things onto the internal memory but with the same probs.
Then I simply looked at using Windows explorer with drag n drop. Looked easy but again, files went missing in the transfer, photos cut in half, music files not recognised as playable, corrupt files and the list goes on. I recommissioned the external mem card 4 times now to no avail. The internal memory was wiped of my files and started again.
After extensive research, time and effort - I can only conclude my earlier finding. This New HTC one M9 is the biggest steaming pile of over rubbish ever offered on the Australian market. I only hope I never meet face to face with a HTC executive - it wouldn't be pretty !!!!
Honestly I really wanted to love this new technology in the M9 but their is nothing to love as its all marketing show and no go.
