I would think there would be a utility in Windows 10 to find duplicate files. I think DOS had a command to do this.

I searched online and there seems to be some archaic programs to do this, but I'd rather not download anything just to do this.

Then I found Ccleaner, which I already have on my machine does this. I'm puzzled though; what Ccleaner finds is apparently an exact duplicate, same size, created at the exact same time.

But when I go to the actual location of these files (following the path that's displayed in Ccleaner), I see a vastly different size for each one, and different creation dates.

I don't think any DOS command can help you find duplicated files one can create a batch script to compare file sizes but this is not good way to find duplicated files. There are lots of good program you can use to find duplicated files check out below url link.

There are a bunch of programs to find dupes in Windows and yes there were batch files in Dos using the FC (file compare) that kind of did the same thing.

 

But if your looking for dupes with the same name scattered over your hard drive, Windows already has this functionality built in.

Click on your yellow folder icon in the taskbar (Windows libraries) the click on "My PC) in the left hand panel. then click on your "C Drive" in the right hand panel.

Last, inside the box on the top right of the window type in the file name and give windows a few seconds. You should then see a list of all the files with the same name.

Have you backed up today? Did you backup your backup?

Thanks. I'm not looking for a specific file. I've got dozens if not hundreds of them scattered all over the hard drive and need to clean it up.

Ccleaner seems to do an adequate job in finding duplicate files. I'm surprised it's not mentioned hardly anywhere.

However, the file size and creation date of the files themselves are different from what Ccleaner says AND different from each other. This is very strange.

I haven't used CCleaner's duplicate file finder feature, but given that I have used a lot of its other features for years I suspect the dup file finder is as highly configurable as the others.

 

There is a chance that all it is doing is searching on file name, which would give you precisely the results you are seeing.  Check on what the settings are set to as it's clear that you want file content matching in the event of file name matches, but that if the contents are not the same then the files should not be considered duplicates.

If you want to find and clean up files the easy way, there’s no better tool for the job than Duplicate Cleaner Pro 4. It might not be free, but unlike the rest, it’s easy to use and comes chock full of features.

I would recommend Duplicate Files Deleter program. It's surprisingly works and the best thing about this program is, it is not popping up for updates or fee or something like spam software that I hate, plus it's user friendly.
