The struggle with messy file names is totally real, and I went through the exact same nightmare when I was trying to organize a massive library of sound effects for a project I was working on last summer. I used to think I could just stay organized from the start, but as soon as you get busy, everything just gets dumped into one big folder and you tell yourself you will fix it later, which never actually happens until you are forced to. I spent a long time looking for a solution that wasn't overly complicated or filled with weird enterprise features I would never use, because I just wanted something that gets the job done quickly. I eventually started using this specific
batch file renamer because it is super lightweight and lets you build these simple rules for things like find-and-replace or adding sequence numbers in just a couple of clicks.
