Scripts, Extensions - what is the distinction?

Hi,

 

What is the difference between an Extension and a Script? They seem to appear in different parts of the program. I have just two entries under Tools > Extensions and seven under Tools > Scripts, which includes the two ‘extensions’. I added the latter myself. And is Add-On yet another term for Extension? (The one chosen for this forum section, I note.) Do they all three simply mean the same entity, namely a Script.

I have many more than seven scripts in one place or another. Should they all be in one folder? Why are they not listed under Tools > Scripts? Is Tools > Extensions the only place to add ‘new’ scripts to Tools > Scripts? Does this overwrite older vesions of those scripts?

Is there one place all this sort of guidance is documented?

Any help will be apprecited.

I didn’t find the right solution from the Internet.
