I'm new to Eagle and trying to use it for some projects I am working on. I started a personal library, but I can't seem to find the actual file it is in. I can see it in the Open dialog in Eagle, but it is not visible in Windows Explorer. The file is present because if I try to create a new file in the library directory by that name, it reports a file already exists. The thing I don't understand is the lock image on the file. I attached a screenshot and marked two of these directories. One of them is an old install of Eagle. What is going on with this?
