I have a rooted Android 11.

Using Termux, or Es File Explorer, I can see all the 284 directories in /data/data.

Unfortunately, many file explorer apps (with root privileges, such as Total Commander, ZArchiver) can only see 2 folders : com.google.android.gms (don't know why), and their own data folder.

I thought this was related to this, but apparently no since I granted the root privileges to both apps...

How could I see all the folders in /data/data using (for example) Total Commander? Doing a chmod 755 in Termux? Or maybe there is a problem with these apps as if they they don't use root privileges if at least one folder/file is visible in "normal user" mode?

  • How do you grant root access to Total Commander / ZArchiver? It works fine Android 10

    In their settings, I selected to read files/folders as root (a pop-up from Magisk asking me if I want to grant - or not - root privileges). They also have a setting "Fix SELinux Context" checked by default, but unchecking this does not seem to solve the issue.

    guess it's related to mount namespaces, the apps does not handle it well. you can set to global in magisk settings for testing purposes

  • @alecxs thanks! Did not know about this option (I think the problem of not be able to see folders in /data/data is due to an update of magisk - changing some settings). Just tried and it works just as I wanted ! Please consider to write an answer to get more reputation ;)

To mark this question as solved.

As @alecxs said, these apps does not handle correctly mounting namespaces, and therefore we need to select in Magisk settings Mount Namespace Mode->Global Namespace instead of Inherit.

  • "By default Magisk inherits the calling process's mount namespace. This can be changed in Magisk Manager. If your root app always need global mount access, use --mount-master when calling su. This can be easily done in libsu by adding a flag in config." -- @topjohnwu on Twitter.
