Hi there, im new to the forum but from a quick search through previous posts i didn't seem to come across an answer to my quest, maybe someone could shed a bit of light on this for me?.
I purchased the 10d g3 with 4 gig of internal memory under the premise that i would be able to use a micro SD for general storage of applications and files while keeping the internal memory freed up.
There is no option to move applications to SD, i don't know if this is possible to do but i kind of hope theres a way of doing so, Does anyone have any suggestions that could help me out?.

the only chance is to swap the internal sd card, with the external one, modifiying the vold.fstab

i didn't even know the internal memory was SD but that being said is this an easy process to follow?

whats life without risks 
Well i guess its about time for me to do some research, im glad to know there is actually a way of doing it, whether or not i mess it up or not is the next part of the challenge!.
I came across this after searching for vold.fstab (didn't have any idea what this was).
Its supposedly the edit used to do the swap but it didn't mention a specific tablet.
Recon its worth giving this a go?
1. Using any file manager, navigate to /etc.
2. Copy vold.fstab to root of your extsd and transfer to pc.
3. Using a text editor (Notepad), edit the following lines:
dev_mount sdcard /mnt/sdcard auto /devices/virtual/block/nand1
dev_mount extsd /mnt/extsd auto /devices/platform/sunxi-mmc.1/mm_host /devices/platform/sw_hcd_host0 /devices/platform/sw-ohci.1 /devices/plaform/sw-ohci.2
TO
dev_mount extsd /mnt/sdcard auto /devices/virtual/block/nand1
dev_mount sdcard /mnt/extsd auto /devices/platform/sunxi-mmc.1/mm_host /devices/platform/sw_hcd_host0 /devices/platform/sw-ohci.1 /devices/plaform/sw-ohci.2
4. Save.
5. Copy edited vold.fstab file back to /etc.
6. Reboot. Done!

the vold.fstab is different on each tablet, you can not aplly the same thing on yours, you need to addapt it.

thanks im glad i asked. I found the location of the vold.fstab file using the file browser on my tablet, and then found out using ES file explorer i can open it up and edit it, reboot and it and hopefully have it working?. I need to root the device first though before i can use ES file explorer but once im at that stage, If i post the info up on here could you give me a hand correctly changing it?

I can try, i can`t offer you a corect value from the start, and it does not work on all the devices.
you need to have root.

#wmt sd
dev_mount sdcard/mnt/sdcard auto/devices/platform/sdmmc.0
#dev_mount sdcard/mnt/sdcard auto/devices/platform/sdmmc1.0
#dev_mount sdcard/mnt/sdcard auto/devices/platform/sdmmc2.0

mcsgeek added this on the 10b g3 forum (NOTE: not 10d, but 10b)
/system/etc/install-recovery.sh (if it's not there then add it)
## swap internal/external sdcard
sleep 2
mount -o remount,rw /
mkdir -p /data/internal_sd
mount -o bind /mnt/sdcard /data/internal_sd
umount -f /mnt/sdcard
mount -t vfat -o umask=0000 /dev/block/mmcblk0p1 /mnt/sdcard
mount -o bind /data/internal_sd /mnt/external_sd
##—--
Add this line to /system/etc/vold.fstab
dev_mount sdcard /mnt/external_sd auto /devices/virtual/mtd/mtd9
And comment out the old dev_mount sdcard line
—--
AND REBOOT
would this work on 10d g3 too?
