i am not sure if it' possible or not. lets say TC process a file name

"Titans 2018 S04E05 1080p WEB H264-CAKES"

now next time if folder monitor has 'Titans 2018 S04E05 1080p WEB H264-NTB" TC will not process it. file match based on "Titans 2018 S04E05 1080p"

If it's the same file, but slightly different filename you can enable in "Settings" -> "Process" -> "General" -> "Check for duplicate by MD5".

It will detect it as duplicate then (obviously must be the same file, but can have different filename).

md5 hash will be different i guess. just different release group releasing.

It will be different since it's not the same file.

Different group might still have better audio or more subtitles (even if resolution is the same). Or even different codec which makes the file size much smaller. You should not just ignore them. People usually want some specific group only (you would get more revenue).
