Remove duplicate files on Mac


Couple of days ago I was going through my Mac and I was surprised to see that the storage is almost full regardless I have not stored any large files when I dived deep into the hard drive then I found that the storage capacity is exhausted because of duplicate files. I have found multiple copies of files which I have not done manually then a question came in my mind that from where exactly these duplicate files came from when I further investigated and found that these duplicates are the results of following activates.

  • Same file download multiple times

Sometimes we download something which is already on our disk or sometimes when we click on the download button and feel that nothing is happening, but the same file is keep getting downloaded multiple times.

  • Multiple backup sets:

We often create backup of our devices on our Mac these devices include our smartphones and flash drives. Taking backup of same device multiple times results in duplicate files.

  • Sharing same file on multiple applications:

We run multiple applications on our Mac but when we share same file or a photo over multiple application it gets multiplies and this results in the creation of multiple duplicates of the same file.

  • Same photographs with different filters:

Eventually I noticed that most of the duplicate files were not documents, videos or system files they were mostly photos. These photos get duplicated when we apply some filters or edits on them. Some cameras click different shots for HDR and normal which keeps creating duplicate copies of photos.

So far you might have understood the major causes of duplication of files it is must to get rid of these duplicates time to time to keep you Mac tuned and to make it work smoother.
