I see that there's a folder named sdcard and another named sdcard2 on a ViewSonic GTablet. If I put the SD card in my PC, the sdcard2 folder is recognized by the PC. If I connect the tablet to the PC via a USB cable, the sdcard folder is recognized on the PC. Neither way allows me to copy any file to the root folder of the tablet (i.e. the folder named /).
Please explain as I'm kind of lost.
