读，向外剪切和拷贝权限

非 ROOT，可以通过 com.marc.files 获得

写，和删除刚写入文件的权限

需 ROOT，可以通过 /storage/self/primary/Android/data 路径获得

• 注意不是 /system/storage/...，该目录并非根目录，也没有 self 路径

Read, cut and copy outwards permission

Non-root，accessible via com.marc.files.

Write and delete permission

Root required. Accessible via /storage/self/primary/Android/data path

• Note that this isn't /system/storage/..., as this is not a root directory, and it doesn't have self path beyond storage.

分析 Analytics

/storage/self/ 路径是一项读写权限为 751 / rwxr-xr-x 的映射路径：

• 设备所有者具有读、写和执行权限
• 组具有读和执行权限
• 其他人（你）具有读和执行权限

通过访问 self 而非 emulated，文件管理器可能获取了设备所有者的权限，或者 self 的访问逻辑没有和 emulated 同步更新，而停留在了安卓 11 版本，导致 Android/data 的写入权限被“破解”

/storage/self/ is a path with filesystem permission of 751 / rwxr-xr-x：

• Device owner could read, write and execute
• Group could read and execute
• Others（you）could read and execute

By accessing self instead of emulated, the file manager app may have gained device owner permission, or self path has a older access logic that wasn't synchronized with emulated, and still works as android 11
