Chapter 6. Filesystems

A shock is when knowing that Android is Linux and knowing the nice Linux filesystems supporting links and UTF8 filenames and then it gets explored that the device tells that it supports just FAT for the memory cards.

Fortunately it can be checked what is really supported by installing a Terminal Emulator app and type cat /proc/filesystems. Its quite obvious that the internal stuff does not run on FAT and therefore also the memory card inserted can have a Linux friendly filesystem as ext4.

Unfortunately this does not mean that the system mounts automatically filesystems other than FAT. And the next hurdle is that mount can needs root permission.
