File used by various operating systems and programs to lock a resource, such as a file or a device; typically contains no data and only exists as an empty marker file, but may also contain properties and settings for the lock.

LOCK files signal to applications that a resource should not be used until the lock is released; this is useful for programs that need to prevent concurrent access to critical resources; for file locking, programs typically create a new file and add the .lock extension for the original filename; for example, a lock file for example.file would be example.file.lock.

LOCK files are commonly seen on Unix-based systems, including Red Hat Linux system file locks; other examples of LOCK files include Mozillas parent.lock file, which locks Windows Firefox profiles, and Apache Web Server lock files, which are created using the LockFile directive..lock
