When this option is set to
on (the default), the
save command saves a document by writing a temporary file, deleting the original file, and then renaming the temporary file to the original name. When this option is set to
off,
save rewrites the original file directly. The default is
on to prevent data loss in the case of insufficient disk space. However, the rename strategy may sometimes fail on certain kinds of network file systems. For those situations, set
saverenames to
off.
