Hi Juan. Which phone are you using? If you are using an Android phone, simply go to Settings > Apps > Downloaded. Check the apps under Downloaded if any have the option "move to SD card". Keep in mind that not all apps are movable that's why it's best to check all apps you downloaded. With regards to files like pictures, simply use a file manager app to cut and paste files to a different location. It's simply like how you do it on a computer.
