How to REALLY hide ALL file extensions in Yosemite?

[poweryn]

There are two options so far that I have seen on the internet and none of them does the job.
The first one is unchecking this box in the finder settings, which does not work at all, or at least for the really popular format like mp4, mov, jpg, pdf...​

The second one is a real joke, you can hide the file extension of a single file only, and not even all the files that has the same extensions which can be done by triggering ⌘I then:​

Even though you can select multiple files to hide their format at the same time, this is not useful at all since you will have to do so every single time you have a new file.

But is there really a way to hide all file extensions using more advanced tools like the terminal?​

So there is no way of doing so??

Yes there is. Just no simple click button and done way for an average joe.

See my postings HERE for more information and an automator script to accomplish what you desire.

Thank you so much wolf I was not expecting a post of such a quality, Isn't this method going to slow down the mac? and will it be run on every startup?

Yes I do imagine the script may slow things down while running and having it run every startup seems a little over the top. If you were to set it up as a startup script I'd probably only have it run on directories where you think you'll be frequently adding new items that you would want extensions hidden, possibly these folders:

"$HOME"/Desktop
"$HOME"/Downloads
"$HOME"/Documents

Something else to note is that most apps lets you hide the extension of new files you create when you first save them with a little check box in the save dialog.
