Renaming tool for pdf and word

but i was wondering, is there was any software similar to mp3tag for tagging and renaming word and pdf documents?

Do you ask for a software mass changing properties in Word or PDF-files under Windows?

This is a list of renaming tools:


I use the Multi Rename option of FreeCommander [available in it after pressing CTRL+M]

It is a very powerful feature - plus it is available in a piece of software than I already used instead of Windows Explorer
