I know that I have on occasion gotten stupid and selected "Remove" after marking images as rejected, when I meant to select Delete From Disk. I believe this means I have image files on my hard drive that no longer appear in the Lightroom catalog, but I don't want them at all. I meant to move them to the trash bin, but, like I said, just hit the wrong button for some reason.
Is there any way I can search for images still in my folders on my hard drive (where I save them when imported in Lightroom) that no longer appear in my catalog? I know this is kind of the opposite problem folks usually have, but I'd like to clean up my hard drive before transfering images to a new computer.
