Finding duplicate files on your Windows PC does not have to be an hour long marathon of searching, comparing and finding anymore. With NoDupe, it is almost to easy to find the duplicate files on your system. When you first start the application you will notice the minimalistic interface. Users who just want to start need to select hard drives or folders on their system before they push the start button.

It is usually not a good idea to search on all hard drives and storage devices for all kinds of duplicate files, considering that you will end up with many duplicate Windows system files in the process.


The Search Type filter helps in this regard. You can switch it from All Files to Music Files or Directories, or click the customise button to add your own filters to the application. You could for instance create a media filter to find duplicates for all your media files, or a document filter for Office documents.

Configuring the right file filters can speed up the duplicate file search tremendously. The customise search menu can be used to add or delete file filters. Each filter consists of a descriptive name and one or multiple file extensions. Only the file extensions listed under the filter will be checked for duplicate files if that filter is selected in the main program window.


NoDupe displays the results in a table. Identical files are shown as groups in the interface, along with their length, filename, directory, extension and data.


You can select individual files for removal and deletion, or use the Auto Mark feature to let the program do that for you. A click on Delete removes the selected files and folders from the system.

Advanced options, linked to from the main interface, can be used to further customize the duplicate file finding process. Here it is possible to select a minimum or maximum file size that you want to be considered, configure file deletion warnings or enable permanent deletion of deleted files.

Windows users looking for a straightforward but nevertheless sophisticated duplicate file finder should take a closer look at NoDupe. The program is compatible with 32-bit and 64-bit editions of the Windows 7 operating system. It can be downloaded from the developer website.

    An even quicker way to open Task Manager is by pressing Ctrl+Shift+Esc.

    Win+Pause used to be the goto shortcut for me since… W95… Ms recently hijacked it and you now get Sysinfo. Device manager is still accessible this way: the second to last link at the bottom.
