二、data 应用和用户数据目录

data 目录 是 应用和用户数据目录 ;

adb           bootchart    local                                                  nfc            system_de
anr           cache        lost+found                                             ota            tombstones
app           connectivity magisk_backup_0b480028f020233d31a2dee75857a11e03983fae ota_package    unencrypted
app-asec      dalvik-cache media                                                  property       user
app-ephemeral data         mediadrm                                               resource-cache user_de
app-lib       dpm          misc                                                   ss             vendor
app-private   drm          misc_ce                                                system         vendor_ce
backup        hostapd      misc_de                                                system_ce      vendor_de

data 目录拥有 rwx 权限 ;

drwxrwx--x  42 system system    4096 2020-11-11 17:10 data

三、mnt 挂载其它设备目录

---

mnt 目录 是 用于挂载其它的设备的目录 ;

drwxr-xr-x  11 root   system     240 1973-11-21 15:33 mnt

外设 , SD 卡等设备 , 都挂载在这个目录中 ;

SD 卡真正的原始目录路径是 /storage/self/primary 目录 ;
