Features: How does CCleaner Duplicate Finder work?

Finding and deleting duplicate files is an effective way to clean up computers, and that’s the reason why CCleaner builds in this useful feature. This feature allows users to remove duplicate documents, videos, movies, photos or other files on your computer.

1. Interface

Once you have launched the program, you can go to “Tools” and choose “Duplicate Finder”, you will find an informative but neat interface. It is easy to use and user-friendly, all the needed icons for customizable settings are arranged in good order, if you need to tweak the settings, just checkmark before the options.

2. Search/Find duplicates

CCleaner allows users to search or find duplicate files in a smart way. Users can search duplicate files that match by name, size, modified date, or content. Even, you can ignore to look through certain files, such as zero-byte files, system files, read-only files, hidden files, even you can specify the min or max file size that you want to ignore to scan.

In addition, during the scanning process, users can include or exclude some drives or folders for searching. For example, if you are quite sure there are lots of duplicates on a drive or in a folder, you can include for scanning, if you don’t want the program look through some files that stored in an important folder, you can exclude for searching.

Yet, CCleaner cannot find all duplicates, there will be some files missing in the duplicates results.

3. Delete duplicates

After the scanning process, CCleaner will find all the duplicates in your selected folder and list them with details, you will know the name, path, size and creation data of these files.

You will have three ways to select the files for deletion.

  • Delete selected files: check the box before this file, then click “Delete Selected”.
  • Delete all duplicates: right click on any file, then click “Select All”, then delete.
  • Delete a particular file type: right click on a file of that particular type, then click “Select All of Type” and delete.

As you may have noticed, though CCleaner offers different solutions to delete files, it doesn’t do that smart as it does in searching duplicate files or as good as other duplicate file finders. Generally speaking, a convenient duplicate finder will offer different options for users to delete duplicates fast and efficiently, such as select all, deselect all, delete the newest, delete the oldest or customize the selection. And its seems in CCleaner, “choosing one by one, then delete” is the safest way to delete duplicate files, since it doesn’t support Preview these duplicates before deletion.

4. Restore Deleted Files

There is a button “Restore results” on the top right corner, this feature is only available when you have paid for its Windows bundle, which includes a data recovery software called Recuva. If not, you will be asked to install this program first.

Before to figure out if CCleaner duplicate file finder tool worth a try or not, we need to have a basic understanding about what does it do and how does it help to find and delete duplicate files.


Should I delete duplicate files in CCleaner? How does CCleaner help to delete duplicate files?

So, here is the conclusion, if your duplicates are not large in quantity, try CCleaner. If you have a lot of duplicate saved on your computer and all of them are important, you will have to take some time and efforts to delete the correct duplicates in CCleaner, since it doesn’t offer a smart way to select files for deletion.
