Thanks Peter.

So to move your Pictures folder to the newly created partition there are two methods. I think the Linux guys will go for a Soft Link. Since they know all about that stuff I will focus on the other method which involves modifying the XDG configuration. This is simply telling the OS where various standard folders are like "Pictures".

First copy the Pictures Folder from its current location (in the Home Folder /home/stellarmate) to the new partition (/media/stellarmate/rootfs/home/stellarmate/Pictures). Use the File Manager if you are not comfortable with the command line.

Type the following at a command prompt:
xdg-user-dirs-update --set PICTURES /media/stellarmate/data/Pictures

My path may not match your so ensure you replace "/media/stellarmate/data/Pictures" with the path to your new Pictures folder.

One more step. We need to create a file called .config/user-dirs.conf.
Enter the following in a command prompt.
cd ~
sudo nano .config/user-dirs.conf (yes the "." is meant to be there, it makes a file/folder hidden in Linux)
Type the following in the file:

enabled=False
filename_encoding=UTF-8

Save using Ctrl X, Yes

then reboot:

sudo reboot

Now the OS will know that your Pictures folder is on your new partition.
