Just like dupeGuru, it allows you to exclude certain folders, subfolders and files from scanning. By default, it ignores system hidden folders and files for safety.

Cisdem Duplicate Finder is better than dupeGuru in removing duplicate files from computer. Due to the huge number of files on the computer, it is very important to preview and compare the file details before performing the deletion, which can prevent us from mistakenly deleting some important files/system data. Cisdem does a good job in this regard. It can also remove duplicates on Android or iOS. dupeGuru is only available on desktop computers yet.
Yes, you can. But the process is cumbersome. After the scan is complete, click Mark > Mark All. Then all the duplicate files will be selected for deletion. It displays the reference files in blue. You can’t mark or delete the blue files. But it allows you to make a selected file into Reference. For example, dupeGuru marks file A as reference file, and B is the copy. If you want to remove A but keep B, you need to select file B, click Actions > Mark selected to reference. Then file A can be deleted.
Despite being freeware now, dupeGuru is professionally designed and good at finding duplicate files on computer. But it is not able to deal with the duplicate files in the Photos app. Luckily, there are other great duplicate file finders available. If your computer is running out of hard drive space, you can free up space by eliminating duplicates on a regular basis.

dupeGuru seems a good duplicate file finder. I wish it supported Mac's Photos. But I will definitely check out the alternative you mention.

After I tried both dupeguru and Cidem duplicate finder, I prefer to choose cisdem duplicate finder not only because of its simple interface, but also the accuracy.
