I want to add more disk space to my computer. My disk partitions are shown below:
How can I extend "Filesystem Partition 3 (105 GB Ext4)" to use the "Free Space (105 GB)", without losing any data?

A better idea is to reboot the system into GParted Live or (my preferred Swiss Army Knife) SystemRescueCD and make the change with GParted.
df -m
so we can see how space is being used and free space. Please post the results in your reply.
