No SD slot? Use OTG.
Google has (so far) not hobbled USB. So put your SD card or Micro SD card in a USB adapter and use an OTG cable. The advantages of having the ability to use any app to edit / delete / move data far outweighs the disadvantage of having a cable attached when necessary.
Incidentally, can anyone suggest why the software used to access an Sd card over USB could not be used to access the SD slot? Wouldn't that solve Google's so-called security issues?
