Renaming source files without breaking link in Premiere? So, I messed up and rushed into a project for work. Instead of giving my files good naming conventions, I worked off a generic file naming convention off the camera. Now I have many edits on premiere but if I want to rename my source files outside of premiere, I find I have to go one at a time. 

Otherwise, if I batch rename them all at once I will have no idea what to relink to what in my project. I've searched and haven't found a solution other than renaming the files inside premiere and consolidating the project to copy to new location and selecting to rename media files to match clip names. 

I don't like this solution because it means I'll have to use the new premiere files. Much appreciated.
I figured it out! It was super easy.

I used Adobe Bridge to batch rename. Very importantly, I left the preserve current filename in XMP metadata option checked. 

BUT before clicking rename, I first clicked preview and exported the CSV file and saved it somewhere safe. This file will help you remember the original file name. In this instance I will know that file 001.png was renamed to 120.png. This is very important.

Now in Premiere, all your renamed files will go offline. If all your files in one location on your drive, this next step is very easy. Just link one file and if you can't remember what you renamed it to, the beauty is that you can quickly search your CSV file in many ways like excel. Then just relink your file to the renamed file that way. Premiere will recognize all your other renamed files because you preserved the XMP meta data. And that's it!
