In settings I can choose internal, sdcard or user defined folder.
With my Xperia Z1 under Kitkat I cannot choose user defined folder.
It's strange because I have a rooted phone and right to read-write everywhere.
The problem is that under Xperia Z1 internal memory=sdcard0, I want to use SDCARD1 (user defined folder) (/storage/sdcard1/android/)
internal memory to put 2go files, it's hard
I must use sdcard1
With other application, it work because when I launch the application, a superu popup ask me to use as root user; but here when I launch Amikit7, no popup. I suppose after Amikit has no right to use sdcard1
