Hi there, I just saw the preference “Stricter recognition of duplicates”. The loose marking of different items as duplicates has always annoyed me slightly.
So I’m keen to switch “Stricter recognition of duplicates” on. Does it come with any noticeable penalty?
The only difference is that you get fewer duplicates, it’s not slower.
Cool. THanks doe the reply.
Is some additional criteria used in this case? As opposed to just usual recognition of duplicates.
Yes, the size in bytes and the document’s type have to be identical too.
Makes sense. I go for stricter detection. 
The less strict comparison has its own advantages, e.g. it marks converted documents (e.g. RTF to PDF) as duplicates as the text is identical.
Interesting Fact! Thanks!
Thank you. I was worried if the loose choice would pick similar files. As far as the text is identify, identifying more duplicates is great for me.
Again - a fantastic function! Saved me a support email to Jim. It even recognizes .pdfs excellent.
would it make sense to allow both options (showing real duplicates with one symbol, and similar files with less stricter recognition of duplicates with another symbol)? so it would be possible to select one or the other or even both in the settings?
It’s the first request of its kind but of course not impossible. Personally I think that this would be overkill as there are already lots of icons causing support frequently. And the See Also is inspector always available to find more or less similar documents, even more than the less stricter duplicate recognition.
dear @cgrunenberg - probably you are right… ! too much icons will be confusing…
