Hi am checking out Directory Opus pior to purchase.
For the folder _test, for every sub folder with "Handout" in it's name, replace *HO.doc with *.doc - and do this recursively for all folders in _text?
I would set up a find for the items to be renamed and run the regular rename tool on the result.
Tbone's suggestion is what I would do as well, at least if it is not something that has to be done every day.
If you need to do it more often, a fairly simple rename script could be written which lets you do everything in one operation, as a single click.
