Duplicate Files: Batch Find and Delete at Once

Duplicate files, like photos, music, videos, documents, are abundant on computer which take up a lot of disk space and even slow down your system if you don't clean them timely. They often occur when you copy a file from one place to another place or you download them twice or more.

So how can you find and delete duplicate files in batch? I believe that you have ever tried the method manually delete copies one by one through Window View. Well, that is really a labor work that you need to pay much time and patience to remove them.

Focus on this article, I'll show you two ways about how to batch find and delete duplicate files at once, including one free method.

Method 1: Use CMD Prompt to batch find and delete duplicates

Now, follow my step.

Step 1: Press win+R simultaneously to bring up the Run panel, and type cmd in it.

Step 2: Find duplicate files. In the CMD window, type "dir drive:\*file's name*.extension /s/b". For instance, I'd like to find duplicate photos that contain string "sushi" in the D Drive, with ".png" extension:

Note:

1: The ".extension" means the type of files, including .txt, .png, .jpg, .doc and so on.

2: Two or more drives are allowed to scan at the same time, for example:

Step 3: Delete duplicate files. Wait for a while and you can see results listed on the panel, with exact location.

Similar to step 2, type "del drive:\*file name*.extension /s/p", and hit Enter.

Note:

1: "/p" means prompt for confirmation before deleting each file (if unnecessary, you can remove it), type "Y/y" or "N/n" and then hit Enter.

2: Multiple disks can be added to delete duplicates.

There is no doubt that this is a bit of complicated. Furthermore, it is a major shortcoming that the CMD is invalid to detect the file with different names but the same content. For advanced detection, you can utilize a detection tool.
