Solution #1: How to Delete Duplicate Videos in Windows 10/11 Using File Explorer?

In this section, we will focus on the manual way to compare files based on appearance, names, and extensions. Now, follow the steps below to eliminate similar files on Windows 11 or 10. 

  • Open the File Explorer on your Windows. Then, go to the location where you want to scan and remove the duplicate files. For Instance: This PC>Downloads.
  • In the right top search bar of the window, enter the file format e.g. .mp4,.avi, etc. After that, press Enter. 
  • Thereafter, the results will be shown in the extension format you entered. Next, you can filter the outcomes according to their name, size, and origin date.
  • In the end, you need to manually go through every video file individually and delete the redundant duplicate file. 

Note: Unlike other Google search results, we have not used the Indexing Options. This is because Indexing is only done to enhance the scanning speed of the engine.
