I am using bluestacks appplayer beta with a rooted android, I want to redirect all writes and reads from one directory to another, how do I do that? I have a terminal available to put commands in..
How do I redirect all writes and reads from /sdcard/whatsapp/ to /sdcard/shared/ on android?

Make a bind mount (use busybox mount if the built-in mount does not support the --rbind option)mount --rbind  /sdcard/shared /sdcard/whatsappYou need to call this command on each reboot.For a permanent solution, you can also replace the directory with a soft/hard link to the target directory:mv /sdcard/whatsapp /sdcard/whatsapp_old    #rename if neededln -s /sdcard/shared /sdcard/whatsapp
