What exact files in "Other Files" is taking up space in my C drive?

I'm new to CCleaner, but I want to see exactly what is taking up almost all of the space on my C drive. It says "Other Files" is taking up 93 percent, but I'd like to know exactly which files are in "Other Files." All the other categories have a sub category drop down except the "Other Files."

Any help would be appreciated.

I guess we're talking about Disk Analyzer? I further guess that Other Files are all those filenames without an extension, or a classifiable extension.
