Change the names of multiple files from the same folder

[Snord]

I have 50 files in a folder that I want to rename. The files in the folder are constantly changing and being updated, so I want to be able to change the file names as they are updated. The idea that I have now is to use the directory tool to bring in all the file names, the RegEx tool to pull the specific portion of the current file name that I want, and then export it via the output tool. However, I'm unable to configure the output tool to rename the files. I tried updating the configuration at the bottom to be "Take File/ Table Name from Field" and "Change File/ Table Name" but that is not working for me.

Any suggestions would be really appreciated.

@ArtApa  LOL.  When I downloaded it most recently, I forgot to change one of the default expressions that I need to modify.
