The default Windows settings don't show hidden files or operating system files, that might be why you don't see everything.
Try WizTree and see if it shows all the folders and files.
They have a Portable zip available, no install needed.
Just unzip, run it, and scan the [C] drive.
Antibody Software - WizTree finds the files and folders using the most disk space on your hard drive

Post a screen print of WizTree if you don't see all folders/files or have any questions.

If you don't use Hibernate you can disable it and that will delete the hiberfil.sys file.
Hibernate - Enable or Disable

I don't know why you have a 32 GB pagefile if you have 16 GB RAM.
You may have a program that needs it, but you can test manually setting the page file to something smaller.
You can manually set the pagefile size, try something like 1 GB minimum.

pagefile.sys is HDD space used as RAM when you max out your RAM (aka swap space). It is typically 2X RAM. Since you have 16GB, this will prob never happen, so you can manually set the swap size lower if it bothers you.

hiberfil.sys is the space allocated for when you hibernate the system, as opposed to just shutting down. If you never use this feature, you can disable hibernate (and reclaim the HDD space used) by opening an elevated cmd window and typing

powercfg -h off

sorry i have just updated my system specs as they are not correct, i have 32gb of ram and a different GPU and now on windows 10 not 7, the only thing that i know that will use this ram is X plane 10 and that is the reason for me going from 16gb to 32gb, so i do now have 4x 8gb of ram not 16gb.

I don't have X plane 10, so i can't comment on if it really needs/uses a 32 GB pagefile.
I would manually set the pagefile to 1 GB minimum, and maximum to 32 GB.
Reboot to make this change.
Run X plane 10 and see if the pagefile increased from the 1 GB minimum.

It may cause an error when you run X plane 10 with the minimum, but then you'll know that it needs the large pagefile.

If it is a problem, you could also test moving the pagefile to a different partition than the [C] drive.

I have 32 GB of RAM and I set my page file to 800MB on the C: drive (to allow for Memory dumps) and let Windows manage an additional page file on another drive F:.

On F, it is only ~ 2400MB when managed by Windows.
