I noticed that in recent versions of macOS, aliases I create are smaller than they used to be. I have a folder full of old aliases whose sizes range from 50 KB to 6 MB, but new aliases seem to be always less than 1 KB.

I want to recreate all my large, old aliases to save disk space. I know I can update an individual alias by finding the file the alias points to, deleting the alias, and option-command-dragging the original to where the alias was. However, this loses the Date Created of the alias, and more steps are needed to preserve the name of the alias if it is different from the original file. Also, this would take too long to do for my hundreds of aliases. How can I shrink my aliases in bulk while preserving the name and Date Created?

There is another, very similar question [Recreate an alias with the same name and timestamp programmatically](https://apple.stackexchange.com/q/269460/21473). The difference is that that question requires an answer that doesn’t change the Date Modified of the alias. I am fine with the Date Modified being updated, as long as the Date Created is unchanged.
