To hide any file , just make a new folder , with .jar name . Like → New Folder.jar . Then put ur files u want to hide in that folder . Then make a folder with same name and write .jad after it → Like New Folder.jad . Then the 1st folder will hide . But this will not hide mp3 & video from the music player . It'll only hide the file from ur phone memory OR memory card . ●● To hide files from music player,without software → Make a folder in your memory card named 'Tones' (without '' ) . Then put ur videos/mp3 files u want to hide , in the folder and update the media library . Now these files are hidden . ● U can also use .otb / .nth after the folder name to change the folder icon .●
