Sometimes, a user may save the same file multiple times unknowingly on his computer, MicroSD card or an external flash drive. Regardless of its size, the file will waste storage memory and it will create disk fragmentation issues. To get rid of such files, you should use the free Auslogics duplicate finder tool (or its alternatives).

This software can be installed in two modes, express and advanced. You should download it from In the express mode, the program automates a series of tasks. It will extract the main application files in the temp folder and copy them to the Programs Folder in Windows OS. It will also create a shortcut on the desktop.

In Advanced mode, ADFF allows you to enter an installation path. You can also prevent the setup from adding a desktop shortcut.

Once the duplicate file remover from Auslogics has been installed on your PC, you can run it by clicking on the program’s desktop shortcut.

The main window of this program features a menu-bar, left sidebar and a dashboard.

In the left sidebar, this program displays a list of windows partitions. Besides the partition name, you’ll find a checkbox.

In the main dashboard, ADFF displays a short description of the software. Below the description, the user will find a wizard tool with these 2 options:

  1. Look for all file types
  2. Look for the files selected below.

The wizard features a back, next and search button. If you select the 1st first option and click on next button, the program will ask you to select a file search criteria. There are 3 search rules:

Size: Users must set the minimum and maximum file size ADFF should ignore or consider while searching your PC.

The above rules will be displayed one by one in the Interface of the file finder Wizard. Once the rules have been selected, the program will prompt you to select one of the below methods for deleting the file:

Recycle Bin: Files will not be completely deleted. They’ll be sent to the Windows trash bin.

Rescue center: Instead of deleting, this duplicate finder will archive the files so that you can retrieve/extract them back when required.

Permanently: The above 2 options will not free up space on the HDD, but this option can.

Once the search rules have been defined, Auslogics duplicate file finder will scan the partitions the user has selected in the left sidebar. While scanning, the program displays the scanning progress, the number of scanned files and time elapsed. The user may pause or stop the scanning task anytime.

The program is fast. On my laptop, it took around 30 seconds to find 845 duplicates. ADFF will list all duplicate files it has found in a 4 column table. The columns are the file name, path, size and the last modified date. You can sort the data by clicking on the column name.

To the right of the table, the duplicate file finder features a preview frame. If you click on any entry in the table, the preview frame will open the file. You can preview the pictures and the contents of the file. If the file is a video, the frame will turn into a video player.

If the program finds a lot of duplicates, selecting them one by one is not possible. In such case, you can make use of the below bulk selection tools:

  • Duplicates by their modification date.
  • One in each group i.e. pictures, videos, documents, etc.
  • Files with a specific extension.
  • All files.

You can also use the inbuilt filter tool.


  • Easy to use.
  • Powerful filters.
  • Can work on files of specific extension, size, and name.
  • Runs on Windows XP, 8, Vista and Win 10 operating systems.
  • Option to back up the duplicate file.


  • Content within the file is not scanned. Thus, it will not identify duplicate documents, PDF, etc.
  • Takes a lot of time in processing compressed archives.
