So, although I'm actually using a Lumia 1520 for these screenshots, let's slum it a little and assume that you have a typical 8GB plus microSD device. This feature deals with the latter, obviously. The takeaways from my previous feature were that living with a sealed 32GB internal storage was do-able, with a little management, that the Lumia 830 with 16GB plus microSD was in the ideal position all round, but that work was also needed for the vast majority of Windows Phones, most with 8GB internal disks and microSD expansion.
