Erwin There are a couple of utilities you might use to do this, such as dbx.exe (sorry, I don't have a copy anymore). It has a user interface including a Modify Structure facility. It'd be easy to make several copies of your dbf then use this to strip out a different set of fields from each copy. Just had a quick browse and at http://www.ozs.com/ there's a utility called WinDBU which may do the trick.
