Any "show in explorer" option in Lightroom?

I clicked Lightroom open two and a half years later since the last time.

I found hundreds of photos I imported years ago, but I can't remember where they are on my hard drive.

Is there any option like "reveal in Explorer" to help me locate them? Or do I have to click every folder, hoping to find them inside?

PS: I even tried to use the Resource Monitor to track the disk activity originating from the Lightroom.exe process, but seems it only reads and writes temp files when I view the photos.
