Hi, this thread is old but I need some fresh info on this. Like several others, I would like to load a large number of photos on my external sd-card and use f-stop to tag them, and, being on KitKat, I’m unable to do so.

As I understand, apps are no longer allowed to write wherever on the external SD-card, but they should be able to write to their own designated folders. So I expect that my F-stop (3.2.1 premium) should be able to create a folder on the sd-card (which is its own and it would have write permissions to it), and should then be able to make changes to the contents of this folder.

However, I am unable to even create such a folder anywhere in extSdCard.
I am using an Xperia Z3 and I see it mentioned that the “fix” from Fstop v3.1 does not work with some Xperia devices. This is the bit I don’t understand. If this indeed due to a KitKat restriction, then logically the problem should not depend on the device and the specific app under consideration. On the same device, Mx Player seems to be able to make changes to files on external sd-card.
So why, then, is F-stop not able to do so?
