Difference between Alias and Duplicate

With the release of InDesign CC 2019, there are some changes to how aliases and duplicates work. This can be a little confusing if you’re not sure what the difference is between the two. In this article, we’ll take a look at what alias and duplicate mean in InDesign, and show you when to use each one.

What is Alias?

Alias is a Mac operating system that was created by Apple Inc. It is based on the Unix kernel and allows users to interact with the system using a graphical user interface (GUI). Alias was first released in 2001 and has since been updated several times. The most recent version, Alias 10.11, was released in 2015. Alias is designed for use on personal computers and laptops. It offers a variety of features, including support for multiple users, a taskbar, and a dock. Alias is also compatible with many software programs, making it a versatile operating system.

What is Duplicate?

Duplicate in Mac Operating System is when you have two or more of the same files on your computer. Duplicate files can take up a lot of space on your hard drive and can slow down your computer. Duplicate files can be created when you download a file more than once, install a program more than once, or even copy a file from one place to another. Duplicate files are not always bad, but if you have too many of them, they can clutter up your hard drive and make it difficult to find the files you need.

Duplicate Finder is a program that can help you find and remove duplicate files from your Mac. Duplicate Finder will scan your hard drive and show you all of the duplicate files it finds. You can then review the list of duplicate files and decide which ones you want to keep and which ones you want to delete. Duplicate Finder is a free program that you can download from the internet.

Difference between Alias and Duplicate

Alias and Duplicate are two terms that are often used interchangeably, but there is a subtle difference between the two. Alias is a term used to describe a new name that has been assigned to something or someone. Duplicate, on the other hand, refers to an exact copy of something. In the case of people, a duplicate would be an identical twin. In the case of objects, a duplicate would be an exact replica. The key difference, then, is that alias is a new name given to something or someone, while a duplicate refers to an exact copy.


In summary, an alias is a unique identifier that points to another table row or entry, while a duplicate is an exact copy of data found in another row. When you are working with your data, it’s important to understand the difference between these two terms and how they will impact your results.
