How to transfer files?

[Cryan]

Hello,

I have made video witch have been recorded to internal (non removable) memory and its size 4.7gb. Because Z1 can not read NTFS system files, the 4.7 faile can not be trasfer to external (removable) memory card, becaus FAT format can not suport biger then 3gb file. I tryed trasfer the file, but everytime i get error message, that file can not be trasfered. So im stuck here, internal memory wont show up on pc when you connect it wit USB, shows just external memory, withc i can not understand why Sony Z1 engineres though about it, that is good idea? The external memory can be removed and pluged to any devoice to transfer files, internal memory can not be removed, so the files stuck there and you can not do anything about it? May any hackers know how to hack to inside system and make internal memyr vievible on pc by connecting USB? Any help would be appreciated.

Thanks

You should be able to see internal memory as well,just enable usb debugging mode and select mtp transfer mode.
