I installed Ubuntu Server to run a local Ark server, and am running out of disk space. When I went to check why (Since the ark install is only ~6GB and I allocated 30GB to the VM) I found that there are 5 filesystems called tmpfs that together use 16GB of HDD space, and another called udev that's using an additional 5GB.
Result of df -h:
Why are these eating up the majority of my space, and how do I move that space over to my filesystem so I can utilize it?
Edit: /dev/sda1 is already 30GB, but I can only use 15GB of it?

tmpfs and udev are virtual file systems. They don't allocate any disk space but dynamically use RAM to store their files. As their content is lost when you shutdown the system they are used for files which should not survive a reboot.
