Asking on behalf of a friend now, she has pictures in here gallery folder she wants to move the whole lot to her external SD card but cant find a way.
She has tried the hold and wait for the option to transfer over this does not work also tried app2sd but that didnt help at all either
She would also like to move some music from PC onto phone could she just take SD card out of phone put it into PC and add the music then put back in phone and it would all be accesable on the SD card?
To move files from phone memory to SD memory inside your phone, your best bet is to use a file manager. You can get one of those on the Google Play Store. OI File Manager is the one I have.
Moving files from your PC to your phone usually involves connecting them physically with a USB lead and treating the phone's SD card as a 'removable disc'. You can, also, use WiFi but that needs another app from the Play Store on your phone plus a corresponding program on the PC. The phone app for Wifi connection is HERE and the corresponding download you need to install on the PC is HERE.
