sda1, sda2, what are these in my partition table?

I'm using Ubuntu on WMware.

My sda1 is in ext4 format, and I assume that it holds my OS and all other files?

What is sda2 and can I delete it and just put all my space into sda1? sda2 is in extended format.

What is the purpose of having this partition as opposed to having a single larger partition?

You can use lsblk to get further information on what each block device is used for.

e.g.

lsblk -f --output MODEL,SERIAL,SIZE,NAME,MOUNTPOINT,KNAME,TYPE,FSTYPE,UUID,LABEL

Find out which partition is mounted on which folder, by typing

sudo cat /etc/fstab

and

mount

Then get a listing of your free disk space with

df -h

This will help you to see which partitions are where.

Most important: Don't move data without knowing what you do. You may cause startup failure on the next boot.
