Im totally new to the smartphone/android topic and very happy that i managed to partition/debrand/root my Desire and flashed LeDroids Rom on it! ^^ ( im a windows XP user ) But i have some questions about my partition and filesystem: I have a 4 GB SDCARD and a 512MB Partition on it for the apps. So i figured out there is a mnt folder that seems to be like an exact copy of my SDCARD folder. How do i know what my partition is ? And how do i know how much space is left there for Apps ? When i plug in my Phone via micro usb and browse my SD card i dont see a MNT folder. Does that mean the MNT folder is the mainpartition (3,5bg?) ? Because when i download a youtube video via jetVD (i was prompted to use a download folder on my SDCARD) it saves the videos under: mnt\sdcard\movies (also my player shows the path to that directory) .. but the movie files are also available under: sdcard\movies Could somebody explain that ? btw: i use the app SUFBS to browse the SDCARD on my Desire.
