How to find and delete duplicate files in Windows

The duplicate file finder scans your hard drive for unnecessary duplicate files and helps you delete them, freeing up space. The following are our choices for the best duplicate file finders, whether you are looking for something easy to use, an application that you might have installed, or a powerful tool with the most sophisticated filters.

You may not use this tool to delete duplicate files found in system folders such as Windows and Program Files. Windows and the program that you are using might need this duplicate file in a different location in order to function properly.

Find and delete duplicate files the easy way with Duplicate Cleaner Pro

If you are really serious about finding and killing duplicate files, your best bet is Duplicate Cleaner Pro, which has a very simple interface with advanced features to delete duplicate files. This software is not free, but they offer a free trial that you can use to test whether you like it. And of course, you don’t need to worry about crapware or spyware.


The Best Easy to Use Tool: Auslogics Duplicate File Finder


Many duplicate file finders are rather complicated, and are packed with lots of different options. Auslogics Duplicate File Finder is different from most, offering a simple interface that guides you through the process. It has other convenient features that everyone should appreciate, such as the default preview pane that allows you to view images, listen to music files, and preview videos so you can see what files are deleted.

Some reviews have knocked Auslogics to combine additional junkware with this application, but they have rather cleaned up their actions ever since. The installer was offered to install Auslogics Driver Updater when we installed the duplicate file finder. Be sure to check any additional software offered during the installation process, because you don’t need a driver update.

This application has reasonable default settings offering a simple wizard that will guide you through the process. This will search for non-system folders on all drives that are connected by default, but you can easily choose which drive and folder you want to search in the sidebar. By default, this will search for images, audio files, video files, archives, and applications, but you can choose only one file type or have all types of files searched. You can easily say it to search for a file with a certain word or text in its name if you are looking for a particular file.

After you do a search, you will see a list of duplicate files and you can easily see their previews and other information. Or, to narrow it down further, you can click the “Filter” button and filter by date, size or file type. Select the file you want to delete and click the “Delete Selected File” button to send it to the Recycle Bin.

The Best Tool You May Have Installed:



CCleaner is a popular tool, so you might have already installed it. The main feature of CCleaner is the removal of junk files, which frees up space on your hard drive by deleting unnecessary temporary files, but also has several other built-in tools, including duplicate file finders.

Open CCleaner and click Tools> Duplicate Finder to find this feature. It is available in all versions of CCleaner, so you don’t need to pay CCleaner Pro to use it.

The default CCleaner setting makes sense, and will allow you to look for duplicate files on drive C: while ignoring system files and hidden files. You can also choose to search for a specific directory by clicking the “Add” button in the Include panel and selecting that folder. Be sure to select the “Include files and subfolders” option while adding a new folder to make sure CCleaner looks for any folder in the folder that you specify as well.

The interface of this tool to view duplicate files is not fancy, and does not have all the same preview options as Auslogics Duplicate File Finder. However, this allows you to easily choose which files you want to delete and even save a duplicate list to a text file. but it is a basic interface that lets you choose which files you want to delete and even saves a list of duplicate files to text files. You can right-click on a file in the list and select “Open folder containing” if you want to see the file itself on your system.

The Best Tool With Advanced Filters: SearchMyFiles


SearchMyFiles is a more sophisticated application with more customizable filters. It can search for files created, modified or accessed only between certain dates and times that you specify, for example.

This tool was made by NirSoft, which also created many other useful free tools that never contained bundled junkware. Like many other NirSoft applications, this is a portable application.

Launch and you will see a complicated search dialog. You will want to select “Duplicate Search” in the Search Mode box at the top of the window and then select the folder to search for by clicking the “Browse” button to the right of the Basic Folder. For example, you can choose C: \ to search the entire C: drive for duplicates. Configure any settings you like and click “Start Search” to search for duplicate files. You will see a list of duplicate files arranged in groups, and you can choose which ones you want to delete.

Many websites recommend DupeGuru as one of the best duplicate file search tools, but it’s no longer officially supported on Windows. You also shouldn’t have downloaded the old Dupe Teacher version – the developer said he saw a bug report on Windows 10 and didn’t have time to fix it.
