The new BTsync 2.3 advertises that it has the feature of storing in the SD card of your Android >=5.0. However, I cannot find such a setting in Settings of the application. There are two options which to do when having the card in CyanogenMod 13 when first time having SD card in the phone: use it as portable SD card or internally. I chose using as a portable SD card. However, I cannot now see any files in the portable SD card when looking the files with PC.
How can you store BTsync data files in SD card?
