Thank you very much for your hints and describing your experiences. Even under Windows I have to change the mode from transferring pictutes to transferring files. And so I did it under MorphOS as well, but so far I could not see any drives on Ambient. But now, with your hint, I will definitely give it another go! :)

Sorry, I completely disagree!
An USB phone connection isn't outdated, it is the usual and common way of transferring files - at least for non tinkerers.

I do not want to transfer pictures or videos via WLAN if it is not necessary. Just like most of the other compter users, I simply want to connect my phone with the USB cable and transfer files - that's it. And I think, an OS should offer this service, just like accessing an 'ordinary' SD card.
