I am trying to figure out why my new Galaxy S3 is saying that the internal memory is almost full. When I open Root Explorer I see a external_sd folder and a sdcard, when I enter the folder storage I have a folder names sdcard0 and a folder named sdcard1. When I enter sdcard0 I find all the same information that is on sdcard folder in the index folder. When I enter the folder sdcard1 I find all the same information that is in the folder external_sd. Anybody knows why these folders are repeated and if I can delete any of them?
