NETCOPY is designed to allow copying files which are in use in a file sharing
network environment. NETCOPY accomplishes this by obtaining a record lock on
the entire file size at the time the copy begins. While the copy is
executing, other programs attempting to access the file will receive record
lock messages, however, other programs are free to expand the size of the file
during the copy. The Destination file is timestamped with the date and time of
the source file at the time the lock was obtained.
