Hello, I am new to android and Galaxy Note. I have a few questions: 1. I have 16GB on my Note and a 16GB memory card. What is the best file organization? Should I store everything in the Note's 16GB memory first before moving to the memory card? Alternatively, should I install Apps on the internal memory while music, video, photo files on the memory card? 2. In Kies air, under file explorer, I see /sdcard with subfolders Android, Application, bluetooth, DCIM, download, Evernote, external_sd, lookout, LOST.DIR, media, Music, Samsung, samsungapps, ScreenCapture, ShareViaWifi, usbStorage, Videomaker. a) Which directory corresponds to the sd memory card? b) What is usbStorage? c) What is the difference between /sdcard and external_sd? Inside external_sd, there is a LOST.DIR directory. Thank you.
