[Q] Use SDCard as Internal memory.

Hi!

I allow myself to open this post because I would like to use my 128GB SDcard as the Internal memory of M8.
Indeed, the "16GB" default storage is too little and some applications (games) are litteraly storage eaters and don't have the feature to move their data to the sdcard.

So, I have see that this trick can be done by modifying the vold.fstab but on the M8 I can't find this file (only a file named fstab.qcom).

Have anyone tried to do this thing and how can it be done?

Thanks in advance!
