For us who use the computer almost every day for work or even personal stuff, we sometimes have the tendency to be slackers in keeping things organized.

One basic thing we neglect to do is keep track of the files we have stored on our computers. What tends to happen is that duplicate files are created.

It is never really easy to keep in mind which ones we already have saved and which ones are new (well not just based on the date that is). Now then comes the time that we need to declutter (since these files eat up storage space) it is a tedious task to filter the duplicates. For the type who is patient enough to go through everything it can be done manually but we have to admit that is so time-consuming and is really not ideal.

There are easier ways to do it like using your computer's Terminal Command or third-party apps that will do the job for you. Read on to find out which is the more efficient way to go about finding duplicate files on your Mac.

Part 1. Old school? Manually find duplicate files on your Mac

Want to be thorough and check yourself you are actually deleting just the duplicates? This can be done through your Mac's Finder window.

You can choose which parameter to sort through i.e. size, file type, date created etc. The ideal way to go about it is by the name of the file which will make it easy for you to see which ones have the same file name. Here are the steps on how to do it manually.

Step 1: Go and open your Mac's Finder window

Step 2: Then go to your Apple menu select File then choose New Smart Folder.

Step 3: To choose which parameters or filters to use click on the "+" icon at the top right corner of the panel. You can even select more parameters to include in your search i.e. file extension, image kind, page count, part of the name of the file, etc.

Part 2. Want to be technical in finding duplicates? Use your Mac's Terminal Window

For people who don't know the basics of using terminal commands this part will be enlightening. Although it is highly advised to be extra careful to not mess up an integral part of your Mac's system. Just follow the simple steps we have for you below.

Step 1: Use the Spotlight search to find the Utilities folder which would allow you to open the Terminal Window.

Step 2: To be able to scan and navigate through all your folders one by one use the cd command followed by the folder name for example cd videos.

Step 3: Copy and paste this command:

find . -size 20 \! -type d -exec cksum {} \; | sort | tee /tmp/f.tmp | cut -f 1,2 -d ‘ ‘ | uniq -d | grep -hif – /tmp/f.tmp > duplicates.txt

Then hit enter (be mindful of what you type on the command line, always double check before proceeding). A text file will be created that consists of all the duplicates in the specified folder that you chose.

The downside of this is you would still need to separate the originals from the duplicates. It just made it easier for you by laying out all the files in the folder but not really finishing the job of making it easier to just take care of the duplicates and get it removed.
