Narrow the job to Pictures or Downloads for a quick first scan.
Scan results
When the scan ends, matches sort under All, Document, Image, Audio, Video and Other. Open one tab and only that kind of copy fills the list.

File details
File Name, File Size, Category and Path columns tell you which copy goes. Right click any row and choose Open to see the file itself first.
Duplicate Cleaner keeps one copy of every file and ticks the rest.

I bought this duplicate file remover tool at the suggestion of a colleague. My internal storage is full, so with the help of this, I have found several duplicate data and deleted them. It is a great tool as you can easily bulk delete unnecessary tools without any issues.
I had a bunch of duplicate photos that I needed to remove. A quick Google search led me to this duplicate remover software. After reading all the specs and reviews, I gave this tool a shot. The interface is pretty simple, so I didn't face any difficulties during the process. I think the tool works really great!
Before you scan
Three short steps give you a clean first scan.
Start with one folder
Choose Pictures or Downloads for a quick first scan. Move to full drives once you trust the result.
Set your filters
Enter extensions like .pdf and .csv, or set a minimum and maximum size in KB, MB or GB.
Know what to ignore
Ignore File skips hidden and read-only files. Leave Windows and Program Files out of every scan.
Mail apps full too? See Gmail storage full after deleting emails and Thunderbird running slow.
Safety checks
Removing files is final, so four habits keep a cleanup safe.
Skip system folders
Programs share identical DLL and config files on purpose. Deleting one breaks the app that needs it.
Pause cloud sync first
Synced folders delete the same files in the cloud and on every linked PC. Pause syncing, clean up, check, then sync again.
Keep a copy outside the PC
Before a large cleanup, copy family photos or work files to an external drive.
Review before Remove
Right click a row and choose Open. Untick any copy you want to keep.
