To copy music from an iPhone, iPod or iPad to a directory on your computer, first open iExplorer on your Mac or PC. Then, go ahead and connect your device with its USB cable to your computer. Once the device is connected, iTunes may prompt you to sync your device - click "No" or "Cancel." Until all of your music have been transferred back to into iTunes we recommend that you avoid syncing the device to iTunes as, in some cases, doing this may result in the permanent loss of data from your device. After your device is connected, iExplorer will display its Device Overview screen. You can return to this home screen at any time by clicking on your device's name in the navigation panel on the left. To get started transferring music, click Music in the middle panel. You can also access your music by clicking Media Library through the sidebar on the left. From here you can browse your entire media library. Navigate through your music, playlists and movies in the left menu. Next, select the tracks or playlist you're looking to transfer to your computer. If you want to copy multiple tracks, click the ones you want while holding the command key (for Mac users) or control key (Ctrl for PC users). At the bottom of the Media Library, click the Transfer from button and a menu will drop down. If you want to export the playlist to a folder, click on Transfer Entire Playlist to Folder. Otherwise, if you're looking to transfer only the selected tracks, click on Export Selected Item(s) to Folder. A dialog box will open, and ask you to choose a folder. Choose a folder, and the transfer will begin!
