How do you remove duplicate files in Windows 10? Here is what you must know. Superfluous duplicate files can waste quite a bit of hard drive storage space.

There are plenty of third-party system maintenance and more specific duplicate file-cleaning utilities for Windows to scan for and erase duplicates with.

Can Windows find duplicate files?

Users of the OS can find duplicate files, but the OS does not offer a native duplicate file finder. This means you must rely solely on third-party tools or alternate methods to identify duplicate files on your PC.

While, in the end, you may be able to find duplicate files on the OS, you must note that the solutions may not be straightforward.
