A
file that no longer has a purpose. For example, when you
uninstall an
application, a few files that make up the application, or were generated by the application, may remain on your
hard disk. These are orphan files since they serve no purpose without the application. In general, you can
delete orphan files, but you should make sure that they truly are orphans because some files, especially
DLLs, may be used by more than one application.
