I need to store on an android tablet or phone some big file : about 30G. To be read by an app as a database.

but because of Fat32 simple copy just fail after 2G.

Could I format my external SD under linux ext2 ? is NTFS format recognized ? Do I have a chance to carry such a file on an external SD ?

  • Generally this is not possible, external storage in most android versions and devices must be Fat32... Can you be more specific as to the device and Android version?

  • i can only guarantee its definitely not possible without modifications. the phones internal storage however can be extended with external sdcard (adoptable storage) but you must not remove this sdcard
