Iterate directories using FileSystemObject

kmlofy · June 18th, 2004, 09:04 AM

I need to update 3500 java files with a copyright statement on my local drive (I'll check them back into changeman later). I'll need to go into each directory (about 100) that may or may not have subdirectories and modify each file. I'm getting caught up in going down the branches.

Has anyone written an routine to walk the directory structure using FileSystemObject?

I found a way to do it, I've pasted it here in case anyone else needs it.
