What is the difference between 'Save as' and 'Save copy'? When I want to save a copy of my blend file, I know two options:


File > Save as
File > Save copy


What is the difference of the two?

And after I press them I see the same result, except difference of 'Save Copy' being checked:




When I point my mouse on it it says for both:
Save As will save the current file as a new file, and you will continue working in that new file. 

Save A Copy will save an exact copy of the file with the entered name, and you will continue working in the file you had open before the operation, leaving the copy exactly the same.
