I have tried copying an .mkv movie file to MiPad (rom, not microsd) but apparently there is 2GB file size limit on Android!? Therefore I cannot copy any file larger than 2GB. Is there any workaround that does not include USB OTG and external usb/drive or streaming via dropbox, etc.? It is really a deal breaker for me as I was looking to copy my favourite movies and tv shows most of which are 6-7 GB in size (per file). Is it possible to format microSD card as NTFS?
