How to remove a geodatabase lock, and how to delete a geodatabase? A database lock is indicative that someone is using the database; I've found that Pro likes to 'hold on' to things and locks probably are one of them. Shut down Pro and restart should do the trick. To delete a database, add the folder that the database is within to your project. Then navigate to that folder, right click on the target database and choose delete.
Why when I change a folder name, it doesn't show the new changes in Windows browser : Thats great question! I just tried renaming a folder in Pro, then closed Pro and opened Windows Explorer and sure enough, the original name persists.
That should just about do it....
