Why is Windows automatically compressing new files?

[Thunder Squirrel]

Recently I noticed that any new files I downloaded or created on my C: Drive would have the little blue arrows at the top right of the icon meaning that Windows was compressing it to save space on the disc. I have a 120 GB SSD, so I cleaned up the drive and currently I have 42.9 GB of free space. That should be plenty of storage left before Windows starts automatically compressing files. Is there an option I need to disable or is it somthing bigger? Whatever it is I would love to get it fixed so any help is appreciate!

open file explorer, right click the c drive, and there should be an option checked talking about compressing files to save space. If that isn't the case tell me.

I see an option that says, "Allow files on this drive to have contents indexed in addition to file properties" but I'm not sure thats what I'm looking for. I dont see anything regarding compressing files to save space under anywhere unfortunatly.
