I believe it's the file access control which determines if a file which is open
can be opened by another process. If a file is opened exclusive, it can not be
opened by another process. If a file is opened non-exclusive, it can be opened
non-exclusively by another process. It is even possible for two processes to
open the same file for non-exclusive updating as long as both processes are able
to recognize and handle the updates made by the other. There are even some high
level exceptions to exclusive access which is how the registry can be backed up
by backup software (at least NT's can) while the OS is running. One can
determine if a file is opened exclusively by attempting to copy it from
explorer.
