You can easily use lsof for that.  To list deleted open
files with link count 0, use this command:   lsof +L1

That depends on the programs that keep the files open.
Some programs close the file handles when you send them
a SIGHUP signal (i.e. "kill -HUP <PIDs>").  The PIDs are
displayed by the lsof command above.  If that doesn't
help, terminate the processes forcibly, if necessary.
When a process terminates, all of its file desciptors
are closed automatically.

Best regards
