Updated to Remove Duplicate Files Tips by Amy on May 27, 2022 | Approved by Daryl Baxter

Ever find your Mac running low on disk space and wonder why it is happening? While the answer may be evident for some heavy users, others might not be expecting to see an entire drive. For many people, the reason for that is an accumulation of duplicate files that they have forgotten about over a period of months and years. However, the fact remains that you need to find and remove these duplicate files and for that, the best solution is a freeware duplicate file finder for Mac.

But the question that immediately arises is which software should you use for this purpose. While there are several great options to choose from, we will share the best free duplicate file finder for Mac.

Part 1. Reasons Why You May Need a Freeware Duplicate File Finder for Mac

Depending on the type of usage you have, the reason for accumulating duplicate files on your Mac can differ quite a lot. However, for most users, these reasons can be condensed into a few broad items, and they are as follows:

  1. Backup files are the most common type of duplicate files. If you have created a backup of your system, you will certainly be finding duplicate files on your system no matter what. While this is easier to see as with each backup, your drive gets more and more full, it is not the only thing causing the issue. You might also want to try making backups on an external drive to avoid losing space on your Mac.
  2. Multiple downloads are another common reason for duplicate files. Sometimes users download the same file multiple times without even realizing and they just sit on their Macs, taking up space. Having this happen frequently can lead to your system space getting used up quite quickly. Using the best free duplicate file finder for Mac can help you remove duplicate JPG files, videos, and documents and save the ones you want.
  3. Copies of the same files on multiple drives are also a reason your drives get used up quickly. Sometimes users save the same item on multiple drives and since there is no way of knowing that a duplicate is being made, the computer simply accepts all files and keeps them stored until the storage starts to get full. Having the best free duplicate file finder for Mac would be the quickest solution to get out of that situation.
  4. Sometimes users share the same file on multiple software and each software saves its own copy of that file, which creates duplicates on the system. This is especially common for photo editing and video editing apps, where you save multiple versions of the same photo or video over time. Eventually, you will need to use a Mac free duplicate file finder to free up the space on your Mac.
  5. Relevant to the first point, multiple backups can also lead to your storage getting used up. If you are obsessed with data security and want to make sure you never lose any data, you might be making multiple backups on your Mac. This could lead to your storage getting full quite quickly, thereby creating a need for a free duplicate file finder for macOS.

Now that you know what can cause duplication of files on your Mac let us talk about the best free duplicate file finder Mac options that you can opt for to free up disk storage.
