How to move Galaxy S4 apps & games data to external SD card?

Err… Directory Bind is not working on Samsung Galaxy S4 Android 4.2 Jelly Bean. How can I move Galaxy S4 applications and games data to external SD card? No worry, FolderMount comes to rescue. In short, FolderMount is Directory Bind replacement. However, it does have its own limitations. Yes, the free version of FolderMount lets you move 3 folders only. 3 folders are enough for me since I will move 1 Android folder only. The sub folder – data and obb will be moved along, right? Sorry, you can’t move these folders but only individual folder within them. Luckily, paid premium version gives you move unlimited folder and can use Android, Android/obb or Android/data as source directories. Note – root access is needed. Not yet root Galaxy S4?

  1. Just a warning to anyone thinking of using this app. When you install this on Galaxy S4 it will ask you to modify or patch the kernel. Doing so will render your phone unstable and semi bricked.

    I had to do a factory reset in order to fix it.

    • Anony,

      Not completely true… I and several others have installed this and allowed that patch on the S4 without issue… Be careful throwing out a blanket claim that this will affect all S4’s just because it affected you.

  2. Hi.Its only this app solve me internal storage problem for I9505 .Its much better than gl to sd app. Thanks for developing great application

  3. First of all, after reboot, FolderMount causes freezes. Second of all, it simply runs the command: mount –bind (get the linux box and read man mount)

    So, basically, anyone can mount this with any, even shell script and will work. No paid app needed. Maybe one day you will see my free app doing this.
