I'm totally confused regarding Android file system and its relation to SD card.
While browsing my Asus Nexus 7 (2013) with file manager
Astro from very root catalog I found directory
sdcard. But there is also catalog
/mnt/sdcard that points to the same location. Why do I need both of them?
I got mixed twice while browsing my rooted
Samsung S4 Lollipop with external SD card.
ES file Explorer. It has :
/sdcard/ with some information that is not on SD card. But why this directory is called SD scard?
/mnt/ /extSdCard/ with card information inside that can be visible on PC if I remove it from phone and put to computer. /sdcard/ again pseudo SD card info.
/storage/ /emulated/0/ that contains /sdcard/ info /legacy/ the same like /emulated/0/ /extSdCard/ linked to real SD card /sdcard0/ again pseudo SD card info.
What is idea of such strange file system organisation?
