Partitions
As said, Android makes use of multiple partitions. In the file system, they are represented by "directories", which serve as their mount-points:
┌─────────────┬───────────────────────────┐
| Partition | Explanation |
├─────────────┼───────────────────────────┤
| /boot | kernel & Co. |
| /cache | app cache |
| /data | user data partition¹ |
| /data/data | app data¹ |
| /dev | devices² |
| /mnt/asec | encrypted apps (App2SD) |
| /mnt/emmc | internal sdcard³ |
| /mnt/sdcard | external sdcard³ |
| /proc | process information² |
| /recovery | used in recovery mode |
| /system | system ROM (read-only) |
└─────────────┴───────────────────────────┘
As for the directories contained, I will again concentrate on a selection; most things here you either cannot touch without having your device rooted.
┌────────────────────┬──────────────────────────────────────────────┐
| Directory | Explanation |
├────────────────────┼──────────────────────────────────────────────┤
| /data/anr | traces from app crashes (App Not Responding) |
| /data/app | .apk files of apps installed by the user |
| /data/backup | Googles Cloud-Backup stuff |
| /data/dalvik-cache | optimized versions of installed apps¹ |
| /data/data | app data² |
| /data/local | temporary files from e.g. Google Play³ |
| /data/misc | system configuration (WiFi, VPN, etc.) |
| /data/system | more system related stuff (certs, battstat) |
| /data/tombstones | more crash stuff ("core dumps") |
└────────────────────┴──────────────────────────────────────────────┘
