I know it will take yrs to fill up my 100G of disk but should I delete old or unnesessary files/folder?
If it's ok which ones should I be removing, file name and path would be helpful.

Please provide some more information about your configuration and check what services you are using.
Most likely a service like proxy, IDS or other is using your space on disk.
Without further information no one can know what service is a candidate to use your disk space.
I'm using Unbound DNS services.
I'm also using Sensei, no other services that I know of.
Here are some screenshots.
