Windows 10: What's the most accurate software to detect duplicate files?

I have tried using CCleaner but it doesn't find truly duplicate files... What I want is something that will tell me which files are true duplicates. If my question is unclear or needs elaboration please let me know.

What's the most accurate software to detect duplicate files?

Hello Kyle. I suggest that you search the web. I saw at least 10 results from 'known' companies when I had the same question after a clean install with problems last October. There were so many unknown companies there as well so I wouldn't dare recommend
one unless I'd tried it first myself.

Hoping this helps.

 

What's the most accurate software to detect duplicate files?

Hi Kyle,

Microsoft Store has a lot of applications/software to offer. You can try to search from there and see which application will suite your need.

Thank you.

 

Consider using one that does this:
-scans the computer and lists duplicate files based on Byte for Byte Comparison or Advanced Scan (CRC, SHA-1 hash). It can find duplicates of any files: documents, music, video, images etc. (MD5 is said to be 'near enough for practical use'- whatever that means).

- and has appropriate filters and options to limit the search (by path, file type, size....), and offer a review before deletion (think pictures, music).

However, most good ones are not free.
Another problem is that many don't state whether they use the matching criteria on their web site.

It's hard to make a general recommendation as some tools specialise in matching media files, for example.
There are plenty of comparison lists.

Note that Ccleaner's comparison has byte-for-byte comparison off by default, which is perhaps why it doesn't seem so accurate.
