"similar filename" should recognize suffix (1), (2) ...

It would be nice if the "similar filename" option included the number suffixes that Windows creates when you try to copy a file into a directory that already has a file with the same name.

Example: I'm copying videos from backup to harddisk. When trying to copy the file "Horrible_holiday_2005.mp4", Windows tells me there's already a file of that name. But I don't know if it's the same movie, and even if the size matches one of them could be corrupted etc. So I tell Windows to copy the file and rename it. Auto renaming results in filename "Horrible_holiday_2005 (1).mp4" (or if that exists, ...(2), ...(3) etc. Or if the filename was "Horrible holiday (2005).mp4" the new file would be named "Horrible holiday (2006).mp4" because Windows is not so smart). Now it would be nice if I could just run DuplicateCleaner over the folder and check if the files are really identical.

I know I could do this with a regex. But as this is the default way Windows marks duplicate files it would make sense if "similar filename" included it.

IMO, you're better off choosing other criteria before using "similar filename".

Knowing what you're doing, I'd think a Content scan, with a "video" Include filter, & maybe a Size range would be more appropriate - at least at first.
Should be quicker (assuming you don't have a huge number of file that happen to have the same sizes, but otherwise are totally un-alike) & will weed out exact duplicates.
Once that is knocked out, you can adjust settings, maybe leave everything alone & select another Size range... Knock out some more... Then revise your search parameters again...

Please tell me this regex. I also need this ability to search duplicates with suffix (1).
