How to Save Data to a Phone’s Micro SD Memory Card
To get the most out of your MicroSD card you may need to have root access to your phone, or the ability to browse through folders on the phone like you would on a computer desktop. For Android phones, this ability may already be present, and different manufacturers allow different levels of access to the directory structure.
And If your phone doesn’t allow this, look for a program called “CyanogenMod” and read up on how to use it to get full access to your phone’s directory structure (and other features). Note that rooting your phone may void your warranty. Cheers!
