This setting is for users on a network to specify whether and how to lock files
that are in use.

Locking provides write access for the first person that opens the file. Anyone
else who opens the file can read it but is denied write access until the first
person closes the file.

An image file is locked when ProdNameShort creates a lock file using the image
base name with a .l_k extension. The lock file is stored in the same directory
as the image file or in the lock file directory if you specify one. When you
insert an image, ProdNameShort searches the image directory (or the lock file
directory) to see if a lock file already exists for that image. If a lock file exists,
then you are prompted that the file is read-only.

If you store lock files in a lock file directory, all raster image files with the
same base name as the inserted image are locked. For example, if you insert
tutor.rlc, a tutor.l_k file is created in the lock directory. This locks the image
that you inserted and any other files with the base name “tutor.”in any
directory.

If you do not specify a lock file directory, the lock file is created in the directory
where the image is saved. In this case, a lock file locks only images in that
directory with the same base name.

NOTE For locking to work properly, everyone on the network must use the same
locking method and directory.
