I'm looking for an app for Android mobile phone to transfer or move files from one folder to another and the posibility to transfer the components of the entire folder by one press selection. Specifically i need it for transfering movies, pictures and music from the internal memory to the external sd card but i prefer it for all types of files. I have tried Astro File Manager and ES File Explorer and didn't succeed to use it. Do you know of any good app? I also need a page with 'How to use' tutorial of the app you will tell me if possible. Also is it a program that automatically moves media files from internal memory to sd card or sd card to internal memory but without selecting folders but selecting categories like 'pictures transfer to Sd card'' or 'videos transfer to SD card' for android phone? That makes two apps.
