Batch adding Metadata to Docs

[AndyTake2]

I have a few hundred word docs which I need to archive, along with thuosands of other documents.

I want to keep the various types together (i.e. all the .doc files, all the .jpg files etc) but still need to access them at times, so I also need to be able to search by subject, which at present is taken care of by simply putting different subjects in different folders.

Is it possible to add meta-data to word docs in a batch process?
I know I can individually open each file and edit the properties from there, but I just want to batch process them all into categories and sort the detail later.
Any tipes?
