>I have my framework classes on a local drive. I want to move them to a network drive. How can I update all my projects at once to look into a new location?

You can open your projects one by one as tables, and in each one of them

replace all name with strtran(name, lcOldFWPath, lcNewFWPath)

I think the paths are stored as lowercase, but you better check or use additional parameters of strtran(). There's also a terminating chr(0) (or maybe not) after the name, but it won't be influenced by strtran.
