I can't open lightroom without quitting my previous catalog. How do I find it and quit it so I can start a new one?

Lightroom won't launch since it says another application has the catalog open. How can I find it to quit that one and open a new catalog?

Go to the location where your Lightroom catalog resides. There will be a file named yourcatalogsname.LOCK. Delete or rename only the LOCK File.

A lock file prevents two programs or two instances of the same program from accessing a database at a time. Lock files are left behind after abnormal closing of the program.
