Help Why oh why can't WE decide which Apps save to Ext Card

[six_h]

CityMaps2Go App as you can appreciate has quite a lot of data (maps) associated with it.
My phone's internal memory is fast reaching capacity so I asked "Ulmon" who created the App how to move it to the external card.
They directed me to "Application Manager", where sure enough there is a button saying "Move To SD Card"..............but it's greyed out!
Typical, most other Apps which take up next to no room at all, all have this button "active".

I have 64GB of prime external card real-estate just begging to be used is it possible to overcome this barrier?

I have already tried moving the folder from phone to card, and then the App can't find the maps!
Help appreciated.

If your phone is rooted, Link2SD will move City Maps to the SD card. But from what it looks like, the maps are still stored in internal storage - /data/media/0/Android/data/com.ulmon.android.citymaps2go/files/maps, to be specific. You could ask them if they could add a choice of internal or external storage to Settings.

(The reason you can't move the maps to external storage with some app now is because that path [the one above] is hard-coded into City Maps 2 Go. An app has to be written to give you the choice to store its data to external storage.)
