How to find and remove Duplicate files with CCleaner


  • If you do not use Match By and Ignore option properly then the results will not come according to your desire. So you’ll need to properly settings up CCleaner Duplicate Finder.
  • Match By options are the most important factor to get accurate results but in case you have enabled all the options checkboxes then the search results will come too much less. So enable only one option. For Example, if you believe you have many duplicate files with the same name then only select the checkbox Name. And If the file name has little difference then It would be good only select the checkbox “Size” because if you search a filename ABCD and another duplicate file name is ABCD_Copy then it will be ignored by Name search but the file size is same so Size option will find the duplicate file. And Also Modified and Content option also plays the important role to find out best-matched results.
  • If you’re searching a duplicate file which size is lower than 1MB then Uncheck the checkbox File Size Under check box otherwise all files under 1Mb will be ignored from Search.

  1. so thousands and thousands of duplicate files found and ccleaner wants me to manually select each and every one!!! I dont care which one it keeps so long as I am left with just one, really ccleaner is rubbish for removing duplicate files, finding them its great I agree, but anymore than a dozen and its a waste of time.
