I know that this is an old topic, but it came up at the top of my search. I was wanting to take an existing project of mine, and make a new project out of it. The new project is going to have many similarities, and it would be the quickest way to get started on the new project. I don’t really want the project and file names to be the same as the old project. It takes a little work, but overall I don’t think that it was too bad.
My project has several sheets. Fortunately for me, all my sheets began with the same name… like “BVS_01_MPU.sch”, “BVS_01_Memory.sch” and “BVS_01_IO.sch”. I used Notepad ++, Find in Files to search for “BVS_01” and replace it with the new name I wanted. This took care of all the references inside the files. Next I used a utility call “Bulk Rename Utility” by TGRMN Software to rename all the file names from “BVS_01” to the new name.
That was it. I opened the project and everything had the new names and opened fine. I hope this helps someone else out.
