How can i transfer APK files from my old SD card to a new micro SD card?
Connect your x10 to your computer with the old 8gb car installed and enable usb debugging
With your PCs file manager copy the entire contents of your x10's SD card to a temporary folder.
Change the cards so the 32gb is installed.
Copy the entire contents of the temp folder onto the new microSD.  


It will be an exact mirror of what you had before.
