Lock files are created when a virtual machine is powered on. Their purpose is to prevent multiple VMware processes from accessing the same virtual machine at the same time. The existence of a lock file indicates to VMware that the associated virtual machine is powered on. If a lock file exists, and an attempt is made to power on the virtual machine, VMware will prevent this and an error message will be displayed. The exact error message will vary, depending on the nature of the lock file, the product in use, and the version of the product.
Lock files are most often located in a virtual machine's directory in error when the virtual machine was shut down unexpectedly and the VMware product in use did not have time to perform the normal routine removal of these files.
