32gb endless one, 100% memory used

I have one of the orginal endless computers with 32gig of memory.

It is showing 100% memory used in the first and second 15g

I cannot delete, I cannot even change settings.

OS 2.5.5
Memory 1.9 GIB
Intel Celeron® CPU N2807 @ 1.58GHz x 2
Graphics Intel Bay Trail x86/MMX/SSE2
OS 32-bit
Disk 15.3 GB

How do I clear up memory?
Can I do a clean install of os 3.x?

The instructions say to update to the latest version of 2.x which I think is 2.6, I am at 2.5.5 and cannot update. If there is a way to update to 3.x I would be jubilant, but I tried to follow the instructions and it failed to even start.
