I prefer to move files one at a time from (my files), its pretty easy, just time consuming. Open my files, tap sdcard, tap the options key, select multiple, now select the files you want moved, tap move, tap the top of the screen and select home, select internal storage and tap move again. (Edit the name of the files so you can identify them easily, I put s in front of mine, then I edit it back out when I'm done.)
SD explorer will ve your best bet to move the files over to your sdcard in the device. Quick tip, razr/maxx is different than you think. You have two SD cards, the removable one is called sdcard-ext.
So move the files off of the 32gb sdcard-ext to the internal storage.
Format the 32 gb SD card by going into settings, storage, scroll down to sdcard, select unmount, format sdcard. It will remount the sdcard.
Now transfer the files with
Your file explorer program.
Now go back into settings, privacy, factory data reset, now its important that you DONT select erase sdcard. follow the prompts and you should be good.
