How to delete unnecessary and junk files from your Mac

If your Mac is becoming sluggish, the first thing to check is whether you are running out of disc space. It is typically recommended that you keep 10% of your entire storage space free on your Mac for the best possible performance. If you’re down to your final few GB, it’s time to perform some housework and reclaim some space.

A Mac is likely to build a big collection of duplicate files that use this valuable space over time, so that’s a smart place to start. However, identifying and removing them one by one might be time-consuming. Therefore, in this post, we will show you faster ways to clean your Mac by removing unnecessary files.

Why does Mac have duplicate files?

Most of the time, these are accidental downloads that are caused by clicking on a link twice, Mail & Messages attachments, a jumbled file system, a terrible habit of dragging things to your desktop, or a variety of other reasons. Unless you’re an extraordinarily conscientious Mac user, duplicates will appear in some form or another.

How to Use the Finder to Find Duplicates

Using the Finder’s Smart Folders function, you may find duplicate files on your system.

  • Begin by launching the Finder app.
  • In the menu, select File > New Smart Folder.
  • In the upper-right corner, click the ‘+’ button.

You may now search for documents, photographs, music, and a variety of other file formats. The important thing is how you sort the findings. Ordering them alphabetically should reveal any obvious duplication.

Just keep an eye on the date to determine if it is a real duplicate – you don’t want to remove the incorrect version of an essential document, for example. (If you can’t see the date, right-click and choose Date Added; you can also add Date Last Opened to ensure you remove the correct one.)

This is achievable, but far from ideal. One problem might be that you have given the same file several names, which this procedure would not detect.

It’s also a time-consuming operation, and the time spent sifting through the huge list of files may be better spent going to the App Store and purchasing software that will discover and safely remove the duplicates for you.
