Photos, videos, voice recordings – these days, our mobile devices such as smartphones, tablets and laptops store all kinds of things. This possibility allows us to reminisce at any time, listen to our favorite music or save entire doctoral theses. At the same time, mobile work is possible via mobile phone and we can send videos and photos to relatives far away, so that the spatial distance hardly matters.
