There's a editor called Ultra Edit 32 that has some nice features. One important feature is macroing. You can record a macro of you editing on file using the search and replace option then saving, then closing the file. Then open every file and just hold the key you binded to the macro. It will edit every file then save and close them.
I upgraded to UBB 6 and my old Avatar mod setting was in the place of the public displayed name. So everyone's name was showing up as the URL to the Avatars. Using UE32 I was able to edit 200 member profiles in less than a minute. Hope that helps.
