Maybe the newer version of the file has another name or location. I tend to use the Terminal for this kind of actions. And I prefer move to delete when experimenting.
It's a bit more complicated. How fast are these really ? how much power can transfer ? and after a few months of usage, which one can do what ? should I measure and sign each one with a specific code ?
When will we get a simple classification of USB-C cables and will we be able to know which cable can charge, how fast, which one can transfer data, how fast...
When something is resisting, I use the Terminal. But be aware that hard deletion like that may "kill" your app. So you may want to save these first, or even read their content with the plutil command.
