ImageExposer requires Superuser and allows you to expose custom disk images instead of the real SD card. It should be usable e.g. for transferring files using the phone over USB while playing music or for preventing people from seeing all the stuff on your sdcard just because you want to take some files home or so.To use this, you will have to: prepare an empty disk image create a partition table in the image create a partition and format it as FAT in the image copy the image to the android device if you didn39;t create it thereThen, open the app, quot;select new image filequot;, choose the image.Alternatively that39;s how I did it, you can expose the empty image right after creating it and then do the partitioning stuff from the PC. Creating an empty image is as easy as running this command on Android using ConnectBot or so:Code:dd ifdevzero oflt;path to the image filegt; bs1024 countlt;size in KBgt;So, for a 100MB image, use something likeCode:dd ifdevzero ofsdcardmyimage bs1024 count102400This app was written by Jann Horn
