Where are photo backups stored on my c drive?

My computer's memory is completely full because of lightroom. Where can I find the folder holding all the backed up copies of my photos so i can delete them? I'm using Lightroom CC. Any tips? thank you.

Go to your Lightroom Preferences, choose the cache tab. Make sure you have NOT checked the Store a copy of all originals button and also do not check the Store a copy of all Smart previews button. Now hit the clear cache button. Done...

I've already done that. It cleared up a couple gigabites, but hardly anything.

In that case you cleared up everything controlled by Lightroom except if you manually set some folders to keep a copy locally. Check how much space it says it is using.

You might actually be dealing with the original images that you imported from. Those are not controlled by Lightroom. What happens when you import is that Lightroom copies the files you are importing to a temporary location and then uploads them to the cloud. As soon as they are imported, Lightroom will delete the temporary copies but will leave in place the originals. So you might need to manually go through your hard drive to find those and delete them as there is no link in Lightroom to those files.
