find duplicate files in windows

Duplicate files can take up space on your computer. Here’s how to delete them and recover valuable storage space. 

But first, what is a duplicate file? 

A duplicate file is a copy of an existing file on your computer or external drive. You can create duplicates documents, images, software, music, and other files. 

Sometimes we create duplicate files in order to save different versions, or to backup important files. Your computer may also create duplicate files without you realizing. 

Here are some common ways duplicate files are created:

  • Sharing a particular file multiple times over email. 
  • Downloading multiple copies of the same file.
  • Creating a backup of some files more than once.
  • Copying a particular folder from one destination to another.
  • If the computer is connected to an external drive and the same file or folder exists in both the drive and the system, then the file is considered to be duplicate.
  • Transferring data from the computer to the phone multiple times.

Duplicates are often created without our knowledge. Basic processes, like file transfers, can create duplicates. Usually, these duplicates have identical file content, extensions, and sizes, but have different file names. 

Why Should We Remove Duplicate Files?

While duplicates themselves do not cause a lot of trouble, over time, their number tends to increase. As a result, it takes up a lot of space on the hard disk, eventually slowing your system down.

These files effectively bring in unnecessary content and files in your computer that can slow down performance. Ideally, it is best to get rid of these duplicate files from the computer.
