How to view the files from /root/data folder?

Question

I want to see the files from /root/data/data folder. Is there any application/trick which can do this?

Answer 1

Short answer

You cannot do that without having your device rooted, as the file permissions won't allow you to list contents there. You will be able to change into /data/data, but you will not see a single thing there.

Longer explanation

While one might be able to access /data/data without root (i.e. change into that directory), permissions are set to forbid listing its contents:

shell@android:/ $ ls /data/data
opendir failed, Permission denied
1|shell@android:/ $ cd /data/data
shell@android:/data/data $ 
shell@android:/data/data $ ls -l /data
opendir failed, Permission denied

This is what happens on a device without root (output created just now on my Cat Stargate 2 running Android 4.1.1). Repeating the same on my HTC Wildfire running CM9 (Android 4.0.4) and having root access enabled looks a little different, and should give us the wanted details (output cut to the necessary stuff):

adb shell
root@android:/ # ls -l /data
drwxrwx--x system   system            2013-02-27 02:01 data

As it is clearly shown, /data/data is owned by the user system group system, with this user and group being the only having full read/write/execute access. Everybody else only has execute permission, enabling all processes to change into that directory. This is necessary for the apps to access their data: They know their package names, and such an app named com.foo.bar can directly jump to /data/data/com.foo.bar which it owns and has full access to.

Answer 2

You can do it with ES File Explorer(Only if your device is rooted)

Step 1:
press menu button --> select Root explorer
Step 2:
(A prompt will popup for giving super User permission) Allow permission
Step 3:
(Another pop-up) Click on Mount R/W ,by default there is Read permission(do this only if you need to write something,else leave it)

Step 4: Access any system folder

Answer 3

Simply use a file manager app like AndroZip File Manager

Keep in mind that you cannot edit the files if you do not have root access. It is not harmful only to read the files though.

Answer 4

You can view Android internal storage files without having root access to your device, using adb shell.

In your case directory/files will be different.

1. Add path to environment variable:

   C:\Users\Mohammad\AppData\Local\Android\sdk\platform-tools  # otherwise cd to that directory
   

2. Open terminal command prompt (Run → cmd)

3. Run command:

   adb shell
   

4. To obtain permission to file system:

   run-as com.scu.healthcare
   

5. You can take backup of entire package:

   adb backup -noapk com.scu.healthcare
   

6. Change to internal storage:

   cd /data/data/com.scu.healthcare/files
   

7. View your file:

   cat ErrorLog.txt
   

8. You can change your file permission:

   chmod 777 /data/data/com.scu.healthcare/files/ErrorLog.txt
   

9. You can view shared preference xml files:

   /data/data/com.scu.healthcare/shared_prefs/Your_xml_files
