or if it is unlikely that two people would access the same image at the same
time from a network drive.
Lock File
Choose this option if you are using a network that does not support DOS
File Sharing or if you are using more than one platform on the network.
This option creates a lock file that denies write access to the image file until
it is closed. This file is not locked by your operating system.
With this method of file locking, if a lock file is present and your system
fails, then you will have to delete the lock file manually. Lock files have an
.l_k extension and the same base name as the image. Lock files are either
in the same directory as the image file or in the specified lock directory.
