I'm struggling to edit an config file for a webserver. The file is a text file, and I can open it in a text editor, but not save it. When I try to save it, it says that another application is using it, but I haven't started the webserver yet.
Is there a way that I can see what process that has a lock on the textfile, or why I can't save the file? I am logged in as adminstrator, and the OS is Windows Vista.
