Removing duplicate files
I don't trust free duplicate file finders. Is there a way to find and delete duplicate files easily from a folder in Windows 10 that does not require using another program?

Well, you could upload files and have their hash computed and do it that way, but that would be gloriously inefficient...
MD5 File - HTML5 File Hash Online Calculator - MD5, SHA1, SHA2 (SHA-256), SHA-384, SHA-512
Then you've got music file matching- and specialised programs - just an example where similar (not identical) files might be identified..
Additional columns in explorer offer nothing useful in this regard.
If I May you could use ccleaner's duplicate finder i use it on my external drive (not C drive) just to weed out most of my junk (my C is only for programs and OS)
Hashing is a good idea since hash algorthims look at file data and not the meta data. Here is a powershell script I put together which should move all duplicates to a folder called "Duplicates" then you can just delete the folder.
Code:path = "C:\Path\Root\Seach" $duplicates = "$path\Duplicates" New-Item $duplicates -ItemType Directory $files = Get-ChildItem -Path $path -File $fileHashes = @() foreach($file in $files) { $thisFileHash = Get-FileHash -Algorithm SHA256 -Path $file.FullName if ($fileHashes.Count -eq 0) { $fileHashes += @($thisFileHash.Hash) } else { $isDuplicate = $false foreach ($fileHash in $fileHashes) { if($fileHash -eq $thisFileHash.Hash) { $isDuplicate = $true break } } if($isDuplicate) { Move-Item -Path $file.FullName -Destination "$($duplicates)\$($file.Name)" } else { $fileHashes += @($thisFileHash.Hash) } } }
