help..!! how do i change my default document directory to another drive
 

i want to change my default document directory to another driver, im using Ubuntu 8.10

Move the folder: mv ~user/Documents /destination
Make a symlink to it: ln -s /destination/Documents ~user/Documents

for that your need to shift your /home location to other partation drive.

use fdisk -l
Then after creating new partation on other drive cp data from /home
Then unmout your original /home drive
Then mount your new drive
Add entry in /etc/fstab to make changes permenent.
