AllDup is the duplicate finder of my choice. It offers several search and compare options.

I usually use the byte by byte option and then select "by hand" which files I want to delete. These deletes are final. They don't show up in the bin.

In the case of MGUs and such many duplicates remain undeleted. Sometimes there is a title entered instead the one generated from the filename, or a different style is selected, or it is simply stored in a different key. So you still need to open some file for a visual comparison. But the preselection using AllDup is very helpful.

I refrain from automatic deletion of duplicates.
