What are Duplicate Files & Why Do They Occur?

Duplicate files are copies of a file you have saved on your computer. They often occur when you copy a file from one place to another or when you save a file twice. For example, if you were to save an image from the internet and then re-open it in Photoshop, it would appear as two separate copies of the same file on your desktop. This can be helpful if you want to keep multiple versions of a document - for example, if you're writing a book and want to keep track of any changes made throughout the process.

However, it can become problematic if you don't know what's causing your computer to create duplicate files in the first place! Besides, they also cover up extra space in your hard drive.

How to Find Duplicate Files on Your Computer using CMD?

There are a few ways to find duplicate files on your computer using CMD. You can use the "DIR" or "DIR /S" command to list all of the files and folders on your computer and then use the "FIND" command to search for duplicate files.

To find duplicate files on your computer using CMD, follow these steps:

1. Open CMD by clicking on Start and typing "cmd" into the search bar. Run it as an administrator.

How to Delete Duplicate Files using CMD?

To delete duplicate files using the del command, type the following command into Command Prompt:

del /s /f *.duplicate
