I can do it by using DSOfile form Microsoft, if you are using W2K. Not shure that DSOfile works in WXP. You can shearch for related threads here, macro examples in SW site an technical explanations about how DSOfile works in the Microsoft site.
But if you are using custom props, DSOfile will not work. You have to have a macro that will batch open the SW files and copy the props to other files.
Take a loock at the PropaGator Software that can do this job (I can't give you details because I never worked with tis software).
