AllSync & AllDup

Thanks. There are photos it doesn't detect - seems to be identical jpg images, same dimensions but different sizes in Mb. Don't know what I'm doing wrong there.

Hi all,

I can't get to grips with this. I have 783 duplicates but all not processed due to being protected.
The info message advised all files selected will prevent processing but how do I select only duplicates?
I just can't see an option for this.
